[css-variables] comments from SVG WG on 20 June 2013 css-variables-1 LCWD

Hello www-style,

Here are the review comments from the SVG WG on the 20 June 2013 LCWD of 
css-variables-1.

1. [This is not a comment on the specification per se, but something 
that came to mind while reviewing.]  The current plan for the 
SVG-in-OpenType proposal is to allow the font to define one or more 
palettes that can be selected from, or to have author defined colour 
values for palette entries. Within the SVG document that defines the 
glyphs, palette colours will be reflected by applying a user agent style 
sheet of the form:

  :root {
    var-color0: rgba(..., ..., ..., ...);
    var-color1: rgba(..., ..., ..., ...);
  }

Do you feel this is an acceptable use of custom properties, or should 
there be a way to reference palette entries that does not use some of 
the space of the normally user defined custom properties?

2. We would like to have the ability to animate CSS Variable values, 
although this is not something we need to see in Level 1.

3. Another feature that we had planned to support as part of SVG 
Parameters, but which could be subsumed by CSS Variables, is the ability 
to pass in variable definitions from a containing document.  For 
example, being able to implement 
http://css-tricks.com/examples/IconFont/ (where colour, shadow, etc. can 
be changed) using SVG documents rather than font glyphs.  This also does 
not need to be solved for Level 1.

4. The SVG WG has no other issues with CSS Variables at this time.

Thanks,

Cameron
