Well, There seem to be two camps on the issue of how Namespaces interact with DTD. ***************************************** Camp1 : Most of this Newsgroup ***************************************** Documents with Namespaces can be validated provided the prefix abbreviations are used consistently. DTD processors are un-aware of Namespaces. <PN:NAME> coexists with <BK:NAME>, because they use different prefixes. DTD processors never convert XML Element names into their "Expanded Form" (See 6.3 of the Namespa This camp seems to be equivalent to saying: "Treat <PN:NAME> as an XML ELEMENT tag with a colon in it." ***************************************** Camp 2 : Tim Bray, Andrew Layman ***************************************** To validate a document that uses namespaces, do all the ELEMENT and ATTRIBUTE handling using the Expanded Names. This group thinks namespaces coexist with DTD's, provided both the DTD and the document instance specify consistent URI's for the namespaces. The actual prefix abbreviations used in the DTD or the document instance don't matter. For example, the DTD could define xmlns:BOOK="uri:book_defn" and then define <!ELEMENT BOOK:NAME ...> while a document instance could define xmlns:BK="uri:book_defn" and use <BK:NAME> Proper Namespace aware code will use the expanded name "uri:book_defn" // "NAME" in handling the element and its definition. ***************************************** Camp 3 : Implemented Namespace Aware Code ***************************************** What does code out there do? -- ============================================================== Mark Tucker tucker_m@r...
