Re: Removal (Time for XMail?)

I have a suspicion, not carefully considered, that ID= attributes can 
cause problems when XML is used as a generalized container for other XML. 
For example, let's consider the case where your e-mail has several 
attachments, each of them XML, and they make conflicting use of the same 
ID names.  As best I can tell, you can work around this as long as you're 
careful about what you validate and how, but as I say, I suspect there are 
some messy edge conditions here.  Certainly there are likely to be 
problems with any tools that take the container document as a whole and 
try to blindly interpret ID attributes. 

I have had this same concern for SOAP, for example, insofar as it serves 
as a generalized packaging framework for assembling XML messages.  Not a 
fatal problem, I think, but probably something that deserves a bit of 
thought.
