I know this has already been committed, but why are we still using
PG_XML_STRICTNESS_LEGACY in xpath.c? As we are always checking
pg_xml_error_occurred() this should no longer be necessary.

It's of course also still in xslt_proc.c, but I have submitted a
separate patch to the ongoing Commitfest, which will resolve that. [1]

Best regards,

btw. it's still looking for a rewiever.
