Subject: what's the value of the document type declaration?
got into a discussion last night with someone discussing docbook transformation (being the party animal that i am), and the question arose as to the value of the document type declaration at the top of the XML file. you know: <!DOCTYPE book ... blah blah ...> while the declaration is, of course, useful for validation, it doesn't technically play a part in the actual transformation. i pointed out the one value that it includes all of the extra entities, so that you can use things like ℵ and ⊕, and so on. but beyond the inclusion of the addition entities, is there some other value for the declaration? just curious. rday -- Robert P.
