So, xml-functions-type-docfix-6.patch.
I changed that language to say "populated with row numbers, starting
with 1, in the order of nodes retrieved from the row_expression's
result node-set."
That's not such a terrible thing to have to say; in fact, it's the
*correct* description for the standard, XQuery-based, XMLTABLE (where
the language gives you control of the result sequence's order).
I followed that with a short note saying since XPath 1.0 doesn't
specify that order, relying on it is implementation-dependent, and
linked to the existing Appendix D discussion.
I would have like to link directly to the <listitem>, but of course
<xref> doesn't know what to call that, so I linked to the <sect3>
instead.
