Although falling largely outside the remit of this Working Group,
there is one aspect of the specification which does concern us: 
suggesting as XML namespace names strings of the form xri://xxx 
given that namespace names must be URIs.

Although the XRI Syntax 2.0 spec. [1] has been a Committee
Specification since late in 2005, we could find no sign of 'xri' 
being registered with the IETF as a URI scheme.  Until this is 
done, it is perhaps not altogether appropriate to treat strings 
beginning 'xri:' as URIs.
