It is still not clear what we mean when we
say that we are going to “use” the XSL reference. Will we or won’t
we support XSL’s three color-function syntaxes?
http://www.w3.org/TR/xsl/slice5.html#expr-color-functions
In addition, I don’t believe that
XSL has a notion of the # hexhexhex syntax. So if we want that, we aren’t
really using XSL syntax, though we might be using XSL color names.
CSS 1 allows basically five syntaxes.
Color names, 3-digit hex codes, 6 digit hex codes, rgb absolute, rgb percentage.
It seems like what we have been informally
describing is actually the HTML 3.2 color model:
http://www.w3.org/TR/REC-html32.html
Are there any known problems with that
model that would prevent us from using it?

Yes, I agree with the XSL (not XSLT)
reference.
CSS3 is not yet a Recommendation, and
interoperable support is
only guaranteed for those referenced by
XSL and the HTML DTD.

I don't have
a decision here. In the absence of input, I am picking the existing XSLT
reference because the list of colors is shorter.
