[xquery-talk] XML Databases that support "Dynamic" XQuery Collections?

FYI on the roadmap of eXist-db is the facility to virtualise collections.
This would meet your requirements, but its not ready today I'm afraid.

I've read and seen, Saxon's approach to collections could meet these needs.
But its general performance will be hindered by not having some kind of
persistent indexing mechanism for the underlying XML documents (as is done
in systems like eXist and MonetDB). Is that correct?
