I'm thrilled to hear that Zope 3 is including XML support.  I am a 
little concerned by the references to XML Schema, though.  Is there 
support for other schema languages, like DTDs, RelaxNG, etc?  Or just 
the W3C XML Schema?  Many in the document markup world (as opposed to 
data markup) have objections to XML Schemas.  I would hate to see Z3 
tied solely to that technology for its XML support.  Also, part of the 
beauty of XML is that in many instances you don't *need* a schema. 
Well-formedness is enough.  Z3 should be able to accomodate those 
use-cases as well.
