yes, seems so.
xpath suposes, that namespaces are declared in xml document where xpath is used,
in this case - in xupdate document.

is it correct to declare xmlns in xupdate directives ?
e.g.:
<xupdate:insert-after xmlns:p="myuri" select="/p:node/p:subnode">...

but content of form generation stylesheet then became huge mesh.

BTW - why xupdate directives are all escaped in attributes,
rather then put as plain xml as children ?

Actually I don't think so. But I'm not sure, you could consult
the XUpdate spec.

Yes, that is true. Unfortunately I don't know a better solution.

No idea. Maybe Michi knows?
