But there’s more…
•How do you know which Infosets allow new names/chars?
•application/xml (RFC 3203) needs clarification
(informal discussions started)
•SOAP is based on RFC 3203…did not explicitly anticipate new content…affects interoperation
•Even old-style content may be labeled as
<?xml version=“1.1”?>.
–Streaming large documents complicates early generation of <?xml version=“1.x”?>
–Not clear whether query can easily check for new content when serializing
–XML interop story compromised:  already deployed software can’t read even old-style content
•WSDL?, RDF? Probably others?
•I may not have the list right, but there clearly are a lot of interrelated issues to consider.
