Thanks for being more specific; the part that I thought you were alluding to and what in fact concerns you turns out to be quite different.

Okay. I see from the link you provided that you have been discussing this on a thread crossposted to www-style@w3.org and public-i18n-core@w3.org - looking at the June archives the thread seems to have died. Accordingly I have copied public-i18n-core@w3.org on this reply, to get further guidance. Okay, so it comes down to character normalization when non-Unicode encodings are used and the character data has not been normalized. I can see that this is potentially an issue in CSS, but for XML where the only two encodings guaranteed to work across XML parsers are UTF-8 and UTF-16, and where use of any other (non codepoint subset - declaring UTF-8 and then using US-ASCII is not relevant here) encoding has always required declaration of the encoding, this seems to be less of a problem. If I misunderstand, perhaps you could provide a well-formed SVG example derived from one of your CSS examples that illustrates the problem? BH> The other differences are quite unimportant, especially since BH> RFC 3986 takes some of these into account. Yes it does, but thanks again for the clarification. -- Chris Lilley mailto:chris@w3.org Chair, W3C SVG Working Group W3C Graphics Activity Lead
