That problem arises because part of the content of biztalk.org is expressed using non-compliant HTML. It has nothing to do with XML compliance. > But let's just say for the sake of argument that the examples on the > site were well-formed XML -- my question is this: Just because the > DOCUMENT examples they show are well-formed XML, isn't it the SCHEMAS > that would be validating those documents that would be "breaking" the > current implementations? That's absurd. You might as well say that SMIL "breaks" XML because it imposes additional restrictions. No, an XML-1.0-compliant parser can't tell you whether a given document is SMIL. Why should it be able to? As long as SMIL documents are well-formed XML (they are), there is no problem. > It was my understanding that, at this time, > any schema syntax-based validation-mechanism, by definition, does not > conform to the XML v. 1.0 Recommendation. Is this not true? The XML 1.0 Rec does not *prescribe* any validation mechanism other than DTDs. Applications can, should, and must require validation above what DTD-validation provides. > Said another way: Since a currently-implemented, XML v. 1.0-compliant > validating parser would not be able to use a BizTalk schema to validate > documents (since BizTalk schemas use syntax that is not specified in the > version 1.0 Recommendation), wouldn't such an existing XML v. > 1.0-compliant parser implementation "break" as a result, unless its > creators had also implemented whatever additional, non-standard (and > therefore proprietary) software that BizTalk requires? "Nonstandard" does not mean proprietary. SAX is not a standard, but it is hardly proprietary. > Wouldn't a more "compliant" BizTalk strategy be to have BizTalk using > DTDs for now, Biztalk restrictions may not be expressible using DTDs, which would not be a deficiency.

As long as the W3C-compliant schemas and the Microsoft schemas have the same meaning, one may freely create Biztalk-compliant documents without fear that they will change meanings. > Also, on a less technical, more practical note: Why would anyone want to > put time into using the BizTalk schemas if they know are going to just > have to redo them again when Microsoft, in good faith, changes the > BizTalk schemas over to the W3C's Schema syntax?
