Based on the concensus at the time the strict data type 'URI' was
denoted in the ABNF as the term 'absoluteURI'. The fact that the
ABNF term isn't called 'URI' was for clarity since that
simple acronym was used to many times within the ABNF.

I.e. the error may be on your part in insisting that since the ABNF
does not contain the term URI then it doesn't apply here. Indeed it
does and the question before everyone is, since the XML Namespace
document attempts to redefine the ABNF term 'URI-Reference' to
something that specifically violates the ABNF and the semantics the
document specifies for those terms, what part of the ABNF will
the next version (if there is a versioning) of the document adhere
to and not attempt to redefine.

As far as I can tell the ABNF gives you really two useful choices: 
'URI-reference' or 'absoluteURI'. 

This leaves you with three choices for moving forward to fix the problem: 
1) pick one of the two ABNF terms
2) say your not using URIs at all
3) rewrite 2396.....

My suggestion is #1 and that it be 'absoluteURI'...
