Is it required that XSLT or DOM implement getElementById() in such a way
that a brute force search for elements with attribute ino:id=xxx is
inferior, other than the constraint that the first match is all that's
needed?

Why couldn't the DB return the retrieved subtree with ino:id defined as an
ID attribute in an internal subset part of the returned document, or in the
infoset or whatever the corresponding location is if the result is returned
as a DOM?  Why would we need a new mechanism where the DB would stick in a
PI that the app would have to know about?
