Re: XLink url factorisation

XLink allows for using XML Base to "factor out" URI bases.  See the 
following for more information:

XLink section on conformance relationship to XML Base:
XLink section on how its href attribute uses XML Base:
XML Base spec:

You can instead use XML entity references to shorten that portion of the 
URI, if you wish; it doesn't require understanding of XML Base, and works 
for all URIs (and all types of strings) regardless of whether XML Base has 
been referenced by the vocabulary-defining application in question (but has 
other restrictions that XML Base does not):

<!DOCTYPE doc [
<!ENTITY uribase1 "http://www.example.com/">
<!ENTITY uribase2 "http://www.example.org/">
     randomAtt2="&uribase2;fileB.xml" />

All your base are belong to us :-),
