Re: [CSS21] Please endorse xml:id

/ Ian Hickson <ian@hixie.ch> was heard to say:
| I haven't yet seen any technical reason for requiring xml:id support of 
| CSS implementations. It doesn't improve _CSS_ implementations at all.

If vendor A has a CSS-for-XML product that supports xml:id and vendor
B has a CSS-for-XML product that does not, then id selectors for
well-formed XML documents are not interoperable across those products.
I think that qualifies as an area where the CSS implementations could
be improved.

I had imagined that if the CSS spec said that it would be a good idea
for CSS-for-XML products to support xml:id, then such interoperability
problems could be avoided.

CSS implementors tell me I am mistaken. Fine.

Chris asked me to make a comment along these lines in response to an
email exchange that we had on the public-xml-id comments list. I have
done so. I gather that the CSS WG's consensus is to reject the
comment. I have neither the energy nor the inclination to pursue this
further so, if and when you do reject the comment, you may record, as
a matter of process, that I am satisfied with that resolution.

| required to support CSS?

CSS makes explicit reference to XML IDs and consequently I think it
should recommend support for xml:id. If xml:id made explicit reference
to styling, I believe I'd be entirely comfortable saying that CSS
should be supported.

                                          norm
