| Umm, why can't the current document contain a catalog?  All non-catalog

No, we agreed that if an element is ignored, all of its descendants
are also ignored. So unless the root element was a recognized element
in our namespace, nothing would happen.

OTOH, we should probably consider what's in the catalog
pseudo-attribute more carefully. I expect the only useful answer is,
"it's a URI". But that means that

  <?oasis-xml-catalog catalog="#catalog"?>

or even

  <?oasis-xml-catalog catalog="http://example.com/catalog.xml#xpointer(...)"?>

are syntactically legitimate.

                                        Be seeing you,
