Toby,

Thanks for the pointer.
I reviewed section 4.1, 5.4.3 and 5.4.4 in 
http://www.w3.org/TR/2008/CR-rdfa-syntax-20080620
and I would like to make sure I understand this properly before changing 
the profile:

1, when the default namespace is http://www.w3.org/1999/xhtml
only reserved values are allowed as non prefixed predicate names.

2, section 4.1 says "the document must explicitly contain an xmlns 
declaration for the XHTML namespace" but
a, does it have to be the default namespace?

b, do we have to check if the qname of a property has a prefix that 
correspond to the XHTML namespace and test if its value is a reserved one?
i.e. should we reject this:
<link rel="xhv:foo" href="http://example.org/page2.html" />

Cheers,
