I am as puzzled as you are.  Yes, it's true, as Andrew writes, that
"ultimately, the processor of a document determines what processing is
done" [cited as the rationale for the decision by the XML Schemas WG to
demote the xsi:schemaLocation attribute to a "hint"].  The same could be
said of any software, which behaves in direct response to the
instructions written by its creators, rather than the prescriptions of
standards.  The role of a standard is to assist in the processes of
predicting how software which claims conformance to it will behave, and
of determining which products are actually conformant.
