So Michael, what does the id() function do in the case stated by Elliotte?
You didn't comment on that, and it all seems a bit strange to me: I mean,
should the XML processor not just return the error stating the input source
is invalid XML, and this simply stops the whole process (i.e. it never gets
to see the id() function)?

See http://www.w3.org/TR/xpath#unique-id

"If an XML processor reports two elements in a document as having the same
unique ID (which is possible only if the document is invalid) then the
second element in document order must be treated as not having a unique ID."
