xml subsetting for protocols is un-blackwhite

[from Minitrue]

XMLPP (Jabber moving through the IETF) pretty much aligns with SOAP 
in its XML variant. The current XMLPP spec draft further disallows 
the predefined entities*. This came up on a TAG thread. However, for 
some, that makes XMLPP un-XML. In the same thread, SOAP is 
considered not un-XML.

In anycase, if SOAP/XMLPP/BEEP are converging on an XML variant, 
sometime this year would be a doubleplusgood time to spec it. And 
Peter Saint-Andre has just mailed the TAG saying XMLPP would follow 
a W3C subset of XML, if one were to exist.

Generally, it seems no-one wants to be thought of doing un-XML, but 
don't want XML altogether. Maybe that's an unfair assessment, but I 
am finding this confusing.
