I agree with Dannes here and I believe that the the natural 'grain' of
an xml database is an xml document ... there will be issues embedding
and checking perms at the node level into eXist itself. You could just
create an xml markup and check at a higher level or you could compose
your documents to more closely align with perms and then provide
'views' of aggregated docs with different perms.

at a minimum we should try to get a handle on usage scenarios for this
kind of thing.
