  I don't understand why you keep citing xml:base while it can't apply
to an xml-stylesheet processing instruction as stated in my answer.
What is your point ? Provide a concrete example please ! If it doesn't
apply this is moot, xml-stylesheet should not be processed, the interpretation
of the href attribute is then out of scope and not covered by any REC then.

  Your initial question is the definition of the base for href in an 
xml-stylesheet. xml:base can't be involved. xml-stylesheet reference 
normatively RFC2396 which tells you what the base is in that context.
What else do you need ?
