The following is a list of mostly editorial Last Call comments on
SVG 1.1 and Mobile SVG Profiles Last Call Working Drafts.  These
comments do not represent any of the W3C Working Groups (such
comments will be/are sent separately), just my own.

Comments on SVG 1.1

- There's a bunch of errors in the SVG 1.1 DTD, besides known
  'xmlns:xlink' problem discussed here.

  - The attribute value for the 'version' attribute of the 'svg' element
    is fixed to "1.0".  I think it should be changed to #REQUIRED to
    allow values like "1.1".

    cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/struct.html#SVGElement

  - The 'baseProfile' attribute is missing in the ATTLIST declaration of
    the 'svg' element.

    cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/struct.html#SVGElement

  - Element type declarations of new elements (solidColor, div, p, span,
    region) are all broken.  For example,

      <!ENTITY % divExt "" >
      <!ELEMENT div (#PCDATA|region|div|p|span|animate|set|animateMotion|
                    animateColor|animateTransform|%divExt;)* >

    should be something like

      <!ENTITY % divExt "" >
      <!ELEMENT div (#PCDATA|region|div|p|span|animate|set|animateMotion|
                    animateColor|animateTransform%divExt;)* >

    i.e. without "|" before %xxxExt;.

    cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/color.html#SolidColorElement

  - The element type declaration of the 'br' element is really broken.
    By default, the current definition

      <!ENTITY % brExt "" >
      <!ELEMENT br (%brExt;)* >

    is the same as

      <!ELEMENT br (  )* >

    which violates the element-content model constraint of XML 1.0.
    Do you want to define it as an empty element (as in XHTML), or
    do you want to allow some contents?

    cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/text.html#RegionElement

  - The parameter entity %solidColorExt; is defined, but %solidExt; is
    incorrectly referenced in the element type declaration of
    the 'solidColor' element.

    cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/color.html#SolidColorElement

   - 'div' and other text-wrapping-related element are declared in
     the DTD but according to the current definition 'div' can only
     appear as a child of another 'div' or 'p' and nowhere else, so
     it's not really usable. "10.18.1 Full Text Content Sets" indicates
     that the 'div' element belongs to the 'TextElements' Content Set,
     then the DTD needs to reflect that definition.

     cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/text.html#id5191993

   - And last but not least, the DTD needs to be modularized.

- In "K.1 Normative references", reference to XLink should mention
  the 27 June 2001 Recommendation version.

  cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/refs.html#ref-XLINK

- In "K.1 Normative references", reference to XPointer should mention
  the 11 September 2001 Candidate Recommendation version.

  cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/refs.html#ref-XPTR

- In "K.2 Informative references", reference to MathML 2.0 should mention
  the 21 February 2001 Recommendation version.

  cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/refs.html#ref-MATHML

- In "K.2 Informative references", reference to MIME types registory
  could be <http://www.iana.org/assignments/media-types/> rather than
  <ftp://ftp.isi.edu/in-notes/iana/ assignments/media-types/>.

- In "K.2 Informative references", reference to UAAG 1.0 should mention
  the 12 September 2001 Candidate Recommendation version.

  cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/refs.html#ref-UAAG

- In "K.2 Informative references", reference to XSL 1.0 should mention
  the 15 October 2001 Recommendation version.

  cf. http://www.w3.org/TR/2002/WD-SVG11-20020215/refs.html#ref-XSL

Comments on Mobile SVG Profiles

- "Appendix B. Attribute Index" indicates that SVG Basic supports
  'unicode-bidi' but not 'direction'.  It doesn't make sense to
  support 'unicode-bidi' without 'direction'.  "10.19.2 Basic Text
  Attribute Sets" of SVG 1.1 indicates that 'direction' is supported
  in the Basic Text Module, and in "Appendix C. Style Property Index",
  the 'direction' property is supported in SVG Basic.  Seems like
  an oversight.

  cf. http://www.w3.org/TR/2002/WD-SVGMobile-20020215/#sec-attind

- In References section, the publication date of SVG 1.0 REC is
  wrong.  It should be 4 September 2001, not 9 September 2001.
