- <p>This CSS Image Values and Replaced Content module has two parts:
- First, it defines the syntax for <i><image></i> values in CSS.
- <i><image></i> values can be a single URI to an image, a list of
- URIs denoting a series of fallbacks, a reference to an element in the document, or
- gradients. Second, it defines properties used to control the
- interaction of replaced content and the CSS layout algorithms.
- These properties can affect the used image resolution for bitmaps,
- the replaced object's orientation, and whether and how to preserve
- the object's aspect ratio.</p>
+ <p>CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. This module contains the features of CSS level 3 relating to the <image> type and replaced elements. It includes and extends the functionality of CSS level 2 [[!CSS21]], which builds on CSS level 1 [[CSS1]]. The main extensions compared to level 2 are the generalization of the <url> type to the <image> type, several additions to the ''<image>'' type, a generic sizing algorithm for images and other replaced content in CSS, and several properties controlling the interaction of replaced elements and CSS's layout models.</p>

-Conformance</h2>
-
- <p>A document or implementation cannot conform to CSS Image Values & Replaced Content Level 3
- alone, but can claim conformance to CSS Image Values & Replaced Content Level 3 if it satisfies
- the conformance requirements in this specification when implementing CSS or
- another host language that normatively references this specification.</p>
-
- <p>Conformance to CSS Image Values & Replaced Content Level 3 is defined for three classes:
- <dl>
- <dt><dfn>minimal</dfn></dt>
- <dd>A device that does not implement CSS Transitions, CSS Animations, nor
- CSSOM may ignore the chapters on Serializing and Interpolating values for
- the purpose of claiming conformance.</dd>
-
- <dt><dfn>transition-capable</dfn></dt>
- <dd>A device that implements CSS Transitions or CSS Animations must conform
- to the <i>minimal</i> class, and additionally must implement the chapter
- on Interpolation.</dd>
-
- <dt><dfn>CSSOM-capable</dfn></dt>
- <dd>A device that implements CSSOM must conform to the <i>minimal</i> class,
- and additionally must implement the chapter on Serialization.</dd>
- </dl>
-
- <p>The conformance requirements are expressed with a combination of
- descriptive assertions and RFC 2119 terminology. The key words "MUST",
- "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT",
- "RECOMMENDED", "MAY", and "OPTIONAL" in the normative parts of this
- document are to be interpreted as described in RFC 2119.
- However, for readability, these words do not appear in all uppercase
- letters in this specification. All of the text of this specification is
- normative except sections explicitly marked as non-normative, examples,
- and notes. [[!RFC2119]]</p>

+Conformance Classes</h3>
+
+ <p>Conformance to CSS Image Values and Replaced Content Module Level 3
+ is defined for three conformance classes:
+ <dl>
+ <dt><dfn title="style sheet!!as conformance class">style sheet</dfn>
+ <dd>A <a href="http://www.w3.org/TR/CSS21/conform.html#style-sheet">CSS
+ style sheet</a>.
+ <dt><dfn>renderer</dfn></dt>
+ <dd>A <a href="http://www.w3.org/TR/CSS21/conform.html#user-agent">UA</a>
+ that interprets the semantics of a style sheet and renders

+ <dd>A <a href="http://www.w3.org/TR/CSS21/conform.html#user-agent">UA</a>
+ that writes a style sheet.
+ </dl>
+
+ <p>A style sheet is conformant to CSS Image Values and Replaced Content Module Level 3
+ if all of its declarations that use properties defined in this module
+ have values that are valid according to the generic CSS grammar and the
+ individual grammars of each property as given in this module.
+
+ <p>A renderer is conformant to CSS Image Values and Replaced Content Module Level 3
+ if, in addition to interpreting the style sheet as defined by the
+ appropriate specifications, it supports all the features defined
+ by CSS Image Values and Replaced Content Module Level 3 by parsing them correctly
+ and rendering the document accordingly. However, the inability of a
+ UA to correctly render a document due to limitations of the device
+ does not make the UA non-conformant. (For example, a UA is not
+ required to render color on a monochrome monitor.)
+
+ <p>An authoring tool is conformant to CSS Image Values and Replaced Content Module Level 3
+ if it writes style sheets that are syntactically correct according to the
+ generic CSS grammar and the individual grammars of each feature in
+ this module, and meet all other conformance requirements of style sheets
+ as described in this module.
+
+<h3 id="partial">
+Partial Implementations</h3>
+
+ <p>So that authors can exploit the forward-compatible parsing rules to
+ assign fallback values, CSS renderers <strong>must</strong>
+ treat as invalid (and <a href="http://www.w3.org/TR/CSS21/conform.html#ignore">ignore
+ as appropriate</a>) any at-rules, properties, property values, keywords,
+ and other syntactic constructs for which they have no usable level of
+ support. In particular, user agents <strong>must not</strong> selectively
+ ignore unsupported component values and honor supported values in a single
+ multi-value property declaration: if any value is considered invalid
+ (as unsupported values must be), CSS requires that the entire declaration
+ be ignored.</p>
+
+<h3 id="experimental">
+Experimental Implementations</h3>
+
+ <p>To avoid clashes with future CSS features, the CSS2.1 specification
+ reserves a <a href="http://www.w3.org/TR/CSS21/syndata.html#vendor-keywords">prefixed
+ syntax</a> for proprietary and experimental extensions to CSS.
+
+ <p>Prior to a specification reaching the Candidate Recommendation stage
+ in the W3C process, all implementations of a CSS feature are considered
+ experimental. The CSS Working Group recommends that implementations
+ use a vendor-prefixed syntax for such features, including those in
+ W3C Working Drafts. This avoids incompatibilities with future changes
+ in the draft.
+ </p>
+
+<h3 id="testing">Non-Experimental Implementations</h3>
+
+ <p>Once a specification reaches the Candidate Recommendation stage,
+ non-experimental implementations are possible, and implementors should
+ release an unprefixed implementation of any CR-level feature they
+ can demonstrate to be correctly implemented according to spec.
+
+ <p>To establish and maintain the interoperability of CSS across
+ implementations, the CSS Working Group requests that non-experimental
+ CSS renderers submit an implementation report (and, if necessary, the
+ testcases used for that implementation report) to the W3C before
+ releasing an unprefixed implementation of any CSS features. Testcases
+ submitted to W3C are subject to review and correction by the CSS
+ Working Group.
+
+ <p>Further information on submitting testcases and implementation reports
+ can be found from on the CSS Working Group's website at
+ <a href="http://www.w3.org/Style/CSS/Test/">http://www.w3.org/Style/CSS/Test/</a>.
+ Questions should be directed to the
+ <a href="http://lists.w3.org/Archives/Public/public-css-testsuite">public-css-testsuite@w3.org</a>
+ mailing list.
+
+<h3 id="cr-exit-criteria">
+CR Exit Criteria</h3>
+
+ <p>For this specification to be advanced to Proposed Recommendation,
+ there must be at least two independent, interoperable implementations
+ of each feature. Each feature may be implemented by a different set of
+ products, there is no requirement that all features be implemented by
+ a single product. For the purposes of this criterion, we define the
+ following terms:
+
+ <dl>
+ <dt>independent <dd>each implementation must be developed by a
+ different party and cannot share, reuse, or derive from code
+ used by another qualifying implementation. Sections of code that
+ have no bearing on the implementation of this specification are
+ exempt from this requirement.
+
+ <dt>interoperable <dd>passing the respective test case(s) in the
+ official CSS test suite, or, if the implementation is not a Web
+ browser, an equivalent test. Every relevant test in the test
+ suite should have an equivalent test created if such a user
+ agent (UA) is to be used to claim interoperability. In addition
+ if such a UA is to be used to claim interoperability, then there
+ must one or more additional UAs which can also pass those
+ equivalent tests in the same way for the purpose of
+ interoperability. The equivalent tests must be made publicly
+ available for the purposes of peer review.
+
+ <dt>implementation <dd>a user agent which:
+
+ <ol class=inline>
+ <li>implements the specification.
+
+ <li>is available to the general public. The implementation may
+ be a shipping product or other publicly available version
+ (i.e., beta version, preview release, or “nightly build”).
+ Non-shipping product releases must have implemented the
+ feature(s) for a period of at least one month in order to
+ demonstrate stability.
+
+ <li>is not experimental (i.e., a version specifically designed
