This is the one that I have issues with. Parsers that are based on the 
xml:base specs determine the base uri of that case to be http://foo.com.
If the behavior for determining the base uri of the document entity is 
really supposed to be determined by an xml:base attribute on the 
document element, then imo, this is something that needs to be addressed 
in the xml:base specs and not elsewhere.

So what you are saying is that currently no parser can be used for these 
tests. Just checked out latest version of Xerces and they don't follow 
your expected behavior either.
