-this chapter that describes how WOFF support is mandated, or how CSS Fonts
-functionality like <code>@font-face</code> can be used to reference Web fonts is
-to be moved, probably into the Text chapter.  An informative reference to the

-<h2 id="Introduction">Introduction</h2>
-
-<p>Reliable delivery of fonts is a requirement for SVG.
-Designers need to create SVG content with arbitrary fonts and
-know that the same graphical result will appear when the
-content is viewed by all end users, even when end users do not
-have the necessary fonts installed on their computers. This
-parallels the print world, where the designer uses a given font
-when authoring a drawing for print, and the graphical content
-appears exactly the same in the printed version as it appeared
-on the designer's authoring system.</p>
-
-<p>SVG utilizes the
-<a href="http://dev.w3.org/csswg/css3-fonts/">WebFonts</a>
-facility defined in
-([<a href="refs.html#ref-CSS3FONTS">CSS3 Fonts</a>]) as a key
-mechanism for reliable delivery of font data to end users. In a
-common scenario, SVG authoring applications generate
-compressed, subsetted WebFonts
-for all text elements used by a given SVG document fragment.</p>
-
-<p>One disadvantage to the WebFont
-facility in the past was that specifications did not require
-support of particular font formats. The result was that
-different implementations supported different Web font formats,
-thereby making it difficult for Web site creators to post a
-single Web site using WebFonts that worked across all user
-agents.</p>
-
-<p>SVG 2 mandates support for Web Open Font Format [<a href="refs.html#ref-WOFF">WOFF</a>], which 
- is now supported in <a href="http://w3c-test.org/framework/review/woff-at/">most user agents</a>. Besides enabling compressed, subsetted WebFonts
-with accompanying metadata for clear licensing, WOFF also benefits from OpenType multilingual features 
-and support for advanced typography. Thus, content authors can author CSS to request discretionary ligatures, 
-swash forms, old-style figures etc. while also ensuring that a font is provided which supports those features.</p>
-
-<p>In SVG 1.1, to provide a common font format for SVG that is guaranteed
-to be supported by all <a
-href="conform.html#ConformingSVGViewers">conforming SVG
-viewers</a>, SVG provideed a facility to define fonts in SVG.
-This facility was called <em>SVG fonts</em>. For backwards compatibility, SVG 2 requires support for a subset
-of SVG Fonts, SVG Tiny Fonts, which has been widely deployed especially for mobile content.</p>
-
-
-<h2 id="FontDescriptions">Describing a font</h2>
-
-<h3 id="FontDescriptionsOverview">Overview of font descriptions</h3>
-
-<p>A font description provides the bridge between an author's
-font specification and the font data, which is the data needed
-to format text and to render the abstract glyphs to which the
-characters map — the actual scalable outlines or bitmaps. Fonts
-are referenced by properties, such as the <a>'font-family'</a> property.</p>
-
-<p>Each specified font description is added to the font
-database and so that it can be used to select the relevant font
-data. The font description contains descriptors such as the
-location of the font data on the Web, and characterizations of
-that font data. The font descriptors are also needed to match
-the font properties to particular font data. The level of
-detail of a font description can vary from just the name of the
-font up to a list of glyph widths.</p>
-
-<p>For more about font descriptions, refer to
-<a href="http://www.w3.org/TR/2011/WD-css3-fonts-20111004/">CSS Fonts Module Level 3</a>.
-[<a href="refs.html#ref-CSS3FONTS">CSS3FONTS</a>]</p>
-
-<h3 id="FontDescriptionsAlternatives">Alternative ways for providing a font description</h3>
-
-<p>Font descriptions can be specified in either of the
-following ways:</p>
-
-<ul>
-  <li>a <a>'font-face'</a> element</li>
-
-  <li id="AtFontFace">an <a href="http://www.w3.org/TR/2011/WD-css3-fonts-20111004/#font-face-rule">@font-face rule</a>
-  ([<a href="refs.html#ref-CSS3FONTS">CSS3FONTS</a>], section 4.1) within a CSS
-  style sheet (only applicable for user agents which support using CSS to
-  style the SVG content)</li>
-</ul>
-
-<h3 id="FontFaceElement">The <span class="element-name">'font-face'</span> element</h3>
-
-<edit:with element='font-face'>
-
-<p>The <a>'font-face'</a> element
-corresponds directly to the <a href="http://www.w3.org/TR/2011/WD-css3-fonts-20111004/#font-face-rule">@font-face facility</a>
-in CSS3 Fonts ([<a href="refs.html#ref-CSS3FONTS">CSS3FONTS</a>], section 4.1). It can be used to describe the
-characteristics of any font, SVG font or otherwise.</p>
-
-<p>When used to describe the characteristics of an SVG font
-contained within the same document, it is recommended that the
-<a>'font-face'</a> element be a
-child of the <a>'font element'</a> element it is describing
-so that the <a>'font element'</a> element can be
-self-contained and fully-described. In this case, any
-<a>'font-face-src'</a> elements within
-the <a>'font-face'</a> element are
-ignored as it is assumed that the <a>'font-face'</a> element is describing
-the characteristics of its parent <a>'font element'</a> element.</p>

-<h2 id="SVGFontsOverview">Overview of SVG fonts</h2>
-
-<p>An SVG font is a font defined
-using SVG's <a>'font element'</a> element.</p>
-
-<p>The purpose of SVG fonts is to allow for delivery of glyph
-outlines in display-only environments. SVG fonts that accompany
-Web pages must be supported only in browsing and viewing
-situations. Graphics editing applications or file translation
-tools must not attempt to convert SVG fonts into system fonts.
-The intent is that SVG files be interchangeable between two
-content creators, but not the SVG fonts that might accompany
-these SVG files. Instead, each content creator will need to
-license the given font before being able to successfully edit
-the SVG file. The <a>'font-face-name'</a> element
-indicates the name of licensed font to use for editing.</p>
-
-<p>SVG fonts contain unhinted font outlines. Because of this,
-on many implementations there will be limitations regarding the
-quality and legibility of text in small font sizes. For
-increased quality and legibility in small font sizes, content
-creators may want to use an alternate font technology, such as
-fonts that ship with operating systems or an alternate WebFont
-format.</p>
-
-<p>Because SVG fonts are expressed using SVG elements and
-attributes, in some cases the SVG font will take up more space
-than if the font were expressed in a different WebFont
-format which was especially designed for compact expression of
-font data. For the fastest delivery of Web pages, content
-creators may want to use an alternate font technology.</p>
-
-<p>A key value of SVG fonts is guaranteed availability in SVG
-user agents. In some situations, it might be appropriate for an
-SVG font to be the first choice for rendering some text. In
-other situations, the SVG font might be an alternate, back-up
-font in case the first choice font (perhaps a hinted system
-font) is not available to a given user.</p>
-
-<p>The characteristics and attributes of SVG fonts correspond
-closely to the font characteristics and parameters described in
-the <a href="http://www.w3.org/TR/2011/WD-css3-fonts-20111004/">CSS Fonts Modules Level 3 specification</a>
-[<a href="refs.html#ref-CSS3FONTS">CSS3FONTS</a>]. In this model,
-various font metrics, such as advance values and baseline
-locations, and the glyph outlines themselves, are expressed in
-units that are relative to an abstract square whose height is
-the intended distance between lines of type in the same type
-size. This square is called the <em>em square</em> and
-it is the design grid on which the glyph
-outlines are defined. The value of the <a>'font-face/units-per-em'</a>
-attribute on the <a>'font-face'</a> element specifies how
-many units the em square is divided into. Common values for
-other font types are, for example, 250 (Intellifont), 1000
-(Type 1) and 2048 (TrueType, TrueType GX and Open-Type). Unlike
-standard graphics in SVG, where the initial coordinate system
-has the y-axis pointing downward (see <a
-href="coords.html#InitialCoordinateSystem">The initial
-coordinate system</a>), the design grid for SVG fonts, along
-with the initial coordinate system for the glyphs, has the
-y-axis pointing upward for consistency with accepted industry
-practice for many popular font formats.</p>
-
-<p>SVG fonts and their associated glyphs do not specify
-bounding box information. Because the glyph outlines are
-expressed as SVG graphics elements, the implementation has the
-option to render the glyphs either using standard graphics
-calls or by using special-purpose font rendering technology, in
-which case any necessary maximum bounding box and overhang
-calculations can be performed from analysis of the graphics
-elements contained within the glyph outlines.</p>
-
-<p>An SVG font can be either embedded within the same document
-that uses the font or saved as part of an external
-resource.</p>
-
-<p>Here is an example of how you might embed an SVG font inside
-of an SVG document.</p>

-<p>The graphics for the <a>'glyph'</a> can be specified using
-either the <a>'d'</a> attribute or arbitrary SVG as
-content within the <a>'glyph'</a>.</p>
-
-<p>If the <a>'d'</a> attribute is specified, then the
-path data within this attribute is processed as follows:</p>
-
-<ul>
-  <li>Any relative coordinates within the path data
-  specification are converted into equivalent absolute
-  coordinates</li>
-
-  <li>Each of these absolute coordinates is transformed from
-  the font coordinate system into the <a>'text'</a> element's current
-  coordinate system such that the origin of the font coordinate
-  system is properly positioned and rotated to align with the
-  <a href="text.html#CurrentTextPosition">current text
-  position</a> and orientation for the glyph, and scaled so
-  that the correct <a>'font-size'</a> is achieved.</li>
-
-  <li>The resulting, transformed path specification is rendered
-  as if it were a <a>'path'</a> element, using the
-  styling properties that apply to the characters which
-  correspond to the given glyph, and ignoring any styling
-  properties specified on the <a>'font element'</a> element or the
-  <a>'glyph'</a> element.</li>
-</ul>
-
-<p>If the <a>'glyph'</a> has child
-elements, then those child elements are rendered in a manner
-similar to how the <a>'use'</a> element renders a
-referenced symbol. The rendering effect is as if the contents
-of the referenced <a>'glyph'</a>
-element were deeply cloned into a separate non-exposed DOM
-tree. Because the cloned DOM tree is non-exposed, the SVG DOM
-does not show the cloned instance.</p>
-
-<p>For user agents that support <a
-href="styling.html#StylingWithCSS">Styling with CSS</a>, the
-conceptual deep cloning of the referenced <a>'glyph'</a> element into a non-exposed
-DOM tree also copies any property values resulting from
-<a href="http://www.w3.org/TR/2011/REC-CSS2-20110607/cascade.html">the CSS cascade</a>
-([<a href="refs.html#ref-CSS21">CSS21</a>], chapter 6)
-on the referenced <a>'glyph'</a> and
-its contents, and also applies any property values on the
-<a>'font element'</a> element. CSS 2.1 selectors
-can be applied to the original (i.e., referenced) elements
-because they are part of the formal document structure. CSS 2.1
-selectors cannot be applied to the (conceptually) cloned DOM
-tree because its contents are not part of the formal document
-structure.</p>
-
-<p>Property inheritance, however, works as if the referenced
-<a>'glyph'</a> had been textually
-included as a deeply cloned child within the document tree. The
-referenced <a>'glyph'</a> inherits
-properties from the element that contains the characters that
-correspond to the <a>'glyph'</a>.
-The <a>'glyph'</a> does not inherit
-properties from the <a>'font element'</a> element's original
-parents.</p>
-
-<p>In the generated content, for each instance of a given <a>'glyph'</a>, a
-<a>'g'</a> is created which carries
-with it all property values resulting from the CSS cascade
-on the <a>'font element'</a> element for the
-referenced <a>'glyph'</a>. Within
-this <a>'g'</a> is another <a>'g'</a> which carries with it all
-property values resulting from the CSS cascade
-on the <a>'glyph'</a> element. The
-original contents of the <a>'glyph'</a> element are deep-cloned
-within the inner <a>'g'</a> element.</p>
-
-<p>If the <a>'glyph'</a> has both a
-<a>'d'</a> attribute and child elements,
-the <a>'d'</a> attribute is rendered first, and
-then the child elements.</p>
-
-<p>In general, the <a>'d'</a> attribute renders in the same
-manner as system fonts. For example, a dashed pattern will
-usually look the same if applied to a system font or to an SVG
-font which defines its glyphs using the <a>'d'</a> attribute. Many implementations
-will be able to render glyphs defined with the <a>'d'</a> attribute quickly and will be
-able to use a font cache for further performance gains.</p>
-
-<p>Defining a glyph by including child elements within the
-<a>'glyph'</a> gives greater
-flexibility but more complexity. Different fill and stroke
-techniques can be used on different parts of the glyphs. For
-example, the base of an "i" could be red, and the dot could be
-blue. This approach has an inherent complexity with units. Any
-properties specified on a text elements which represents a
-length, such as the <a>'stroke-width'</a> property, might
-produce surprising results since the length value will be
-processed in the coordinate system of the glyph.</p>

-
-<edit:with element='missing-glyph'>
-
-<p>The <a>'missing-glyph'</a> element defines the graphics to use if
-there is an attempt to draw a glyph from a given font and the given
-glyph has not been defined. The attributes on the <a>'missing-glyph'</a>
-element have the same meaning as the corresponding attributes on the

-<h2 id="GlyphSelectionRules">Glyph selection rules</h2>
-
-<p>When determining the glyph(s) to draw a given character sequence, the
-<a>'font element'</a> element is searched from its first <a>'glyph'</a>
-element to its last in logical order to see if the upcoming sequence
-of Unicode characters to be rendered matches the sequence of Unicode
-characters specified in the <a>'glyph/unicode'</a> attribute for the
-given <a>'glyph'</a> element. The first successful match is used. Thus,
-the "ffl" ligature needs to be defined in the font before the "f" glyph;
-otherwise, the "ffl" will never be selected.</p>
-
-<p>Note that any occurrences of <a>'altGlyph'</a> take precedence over
-the above glyph selection rules within an SVG font.</p>
-
-<h2 id="KernElements">The <span class="element-name">'hkern'</span> and <span class="element-name">'vkern'</span> elements</h2>
-
-<p>The <a>'hkern'</a> and <a>'vkern'</a> elements define kerning
-pairs for horizontally-oriented and vertically-oriented pairs
-of glyphs, respectively.</p>
-
-<p>Kern pairs identify pairs of glyphs within a single font
-whose inter-glyph spacing is adjusted when the pair of glyphs
-are rendered next to each other. In addition to the requirement
-that the pair of glyphs are from the same font, SVG font
-kerning happens only when the two glyphs correspond to
-characters which have the same values for properties <a>'font-family'</a>,
-<a>'font-size'</a>, <a>'font-style'</a>, <a>'font-weight'</a>,
-<a>'font-variant'</a>, <a>'font-stretch'</a>, <a>'font-size-adjust'</a>
-and <a>'font property'</a>.</p>
-
-<p>An example of a kerning pair are the letters "Va", where the
-typographic result might look better if the letters "V" and the
-"a" were rendered slightly closer together.</p>
-
-<p>Right-to-left and bidirectional text in SVG is laid out in a
-two-step process, which is described in <a
-href="text.html#RelationshipWithBiDirectionality">Relationship
-with bidirectionality</a>. If SVG fonts are used, before
-kerning is applied, characters are re-ordered into
-left-to-right (or top-to-bottom, for vertical text) visual
-rendering order. Kerning from SVG fonts is then applied on
-pairs of glyphs which are rendered contiguously. The first
-glyph in the kerning pair is the left (or top) glyph in visual
-rendering order. The second glyph in the kerning pair is the
-right (or bottom) glyph in the pair.</p>
-
-<p>For convenience to font designers and to minimize file
-sizes, a single <a>'hkern'</a> and
-<a>'vkern'</a> can define a single
-kerning adjustment value between one set of glyphs (e.g., a
-range of Unicode characters) and another set of glyphs (e.g.,
-another range of Unicode characters).</p>
-
-<p id="HKernElement">The <a>'hkern'</a> element
-defines kerning pairs and adjustment values in the horizontal
-advance value when drawing pairs of glyphs which the two glyphs
-are contiguous and are both rendered horizontally (i.e.,
-side-by-side). The spacing between characters is reduced by the
-kerning adjustment. (Negative kerning adjustments increase the
-spacing between characters.)</p>
-
-<p id="VKernElement">The <a>'vkern'</a> element
-defines kerning pairs and adjustment values in the vertical
-advance value when drawing pairs of glyphs together when
-stacked vertically. The spacing between characters is reduced
-by the kerning adjustment.</p>

-    A font consists of a collection of glyphs together with the
-    information (the font tables) necessary to use those glyphs to
-    present characters on some medium. The combination of the
+  
+  <p>Reliable delivery of fonts is a requirement for SVG.
+Designers need to create SVG content with arbitrary fonts and
+know that the same graphical result will appear when the
+content is viewed by all end users, even when end users do not
+have the necessary fonts installed on their computers. This
+parallels the print world, where the designer uses a given font
+when authoring a drawing for print, and the graphical content
+appears exactly the same in the printed version as it appeared
+on the designer's authoring system.</p>
+
+<p>SVG utilizes the

+facility defined in
+([<a href="refs.html#ref-CSS3FONTS">CSS3 Fonts</a>]) as a key
+mechanism for reliable delivery of font data to end users. In a
+common scenario, SVG authoring applications generate
+compressed, subsetted WebFonts
+for all text elements used by a given SVG document fragment.</p>
+
+<p>One disadvantage to the WebFont
+facility in the past was that specifications did not require
+support of particular font formats. The result was that
+different implementations supported different Web font formats,
+thereby making it difficult for Web site creators to post a
+single Web site using WebFonts that worked across all user
+agents.</p>
+
+<p>SVG 2 mandates support for Web Open Font Format [<a href="refs.html#ref-WOFF">WOFF</a>], which 
+ is now supported in <a href="http://w3c-test.org/framework/review/woff-at/">most user agents</a>. Besides enabling compressed, subsetted WebFonts
+with accompanying metadata for clear licensing, WOFF also benefits from OpenType multilingual features 
+and support for advanced typography. Thus, content authors can author CSS to request discretionary ligatures, 
+swash forms, old-style figures etc. while also ensuring that a font is provided which supports those features.</p>

+    A font consists of a collection of glyphs together with other
+    information (collectively, the font tables) necessary to use those glyphs to
+    present characters on some visual medium. The combination of the
     collection of glyphs and the font tables is called the <em>font
     data</em>. The font tables include the information necessary to
     map characters to glyphs, to determine the size of glyph areas and
-    to position the glyph area. Each font table consists of one or
+    to position the glyph area. <!-- next sentence is loose and should be impoved -->
+    Each font table consists of one or
     more font characteristics, such as the font-weight and
     font-style.

     The geometric font characteristics are expressed in a coordinate
     system based on the EM box. (The EM is a relative measure of the
     height of the glyphs in the font.)  The box 1 EM high and 1 EM
