I was answering from the SGML point of view. A document containing <A NAME="fubar" ID="fubar">...</a> is perfectly valid if ID is declared as ID and NAME is declared as CDATA. AND all of the specifications state quite clearly that they DO occupy the same namespace. The specs are probably referring to the namespace inside browsers. If a browser does not put them in the same namespace, then the browser is in error. No, for my money the spec is in error because ID and CDATA do not occupy the same namespace in SGML. In HTML, HREF and NAME occupy a common namespace; ID and any IDREF attributes would occupy another. Unless someone just changed the spec. But the HTML spec and browsers' observance of it has now deteriorated to such a low level that it really doesn't matter a damn. If you want to treat them as the same namespace you are at liberty to do so. Just don't expect a validator to resolve IDs to NAMEs because they won't: HTML 4 says <!ELEMENT A - - (%inline;)* -(A) -- anchor --> <!ATTLIST A %attrs; -- %coreattrs, %i18n, %events -- charset CDATA #IMPLIED -- char encoding of linked resource -- name CDATA #IMPLIED -- named link end -- href %URL; #IMPLIED -- URL for linked resource -- target CDATA #IMPLIED -- where to render resource -- rel CDATA #IMPLIED -- forward link types -- rev CDATA #IMPLIED -- reverse link types -- accesskey CDATA #IMPLIED -- accessibility key character -- shape %Shape rect -- for use with OBJECT SHAPES -- coords %Coords #IMPLIED -- for use with OBJECT SHAPES -- tabindex NUMBER #IMPLIED -- position in tabbing order -- onfocus %Script; #IMPLIED -- the element got the focus -- onblur %Script; #IMPLIED -- the element lost the focus -- > where attrs includes coreattrs which says: <!ENTITY % coreattrs "id ID #IMPLIED -- document-wide unique id -- class CDATA #IMPLIED -- space separated list of classes -- style CDATA #IMPLIED -- associated style info -- title CDATA #IMPLIED -- advisory title/amplification --" > ///Peter
