Elsewhere in the Rec a clear distinction is made between character references and entities. The Character Reference behavior is just to append, not to do any recursive normalizing. But the paragraph on replacing spaces with a single space only applies to #x20 spaces, not to any other kind of whitespace So the tab wouldn't get removed, as you say. I wonder if this was an error or intended? The text in the Rec is "If the declared value is not CDATA, then the XML processor must further process the normalized attribute value by discarding any leading and trailing space (#x20) characters, and by replacing sequences of space (#x20) characters by a single space (#x20) character." Maybe they intended "...sequences of whitespace..." instead. Anyone know for sure which way this was supposed to read? Tom Passin xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
