This is interesting. One small thing I'm not sure I get right is that 
you have this grammar:

    qnameURN               = "qname" ":" prefix ":" localname ":" uri
    prefix                 = ncname / "" / "*"

And right afterwards one of the examples is:

   urn:qname:Reject:http://w3.org/2002/xkms#

(for a QName with no prefix). Somehow that seems wrong, especially 
considering the verbiage about the "fourth part" above, since there no 
longer is a fourth part in the above example (which also becomes 
impossible to parse unambiguously without validating that you have a 
correct URI at the end, provided it even is generally possible).

Am I correct to infer that the example should be:

   urn:qname::Reject:http://w3.org/2002/xkms#

and if not, may I suggest that it become that?
