I thought about doing something like this. The problem is that the XDB
is designed as a layer that hides the details of the backend
implementation. So what would the search string look like? For LDAP, its
a filter. For an SQL backend, it might be a certain SELECT query. There's
no easy way to do it without knowing something about the backend.

What would be really good, though a significant development effort,
would be an implementation of something like XML Query (see
http://www.w3.org/XML/Query). I haven't looked into this in any depth,
but it is quite interesting. I will do some reading.

I am also aware of some new Data Management components (aka XDB++) in
the works, though I'm not aware of their capabilities. Perhaps one of
the developers on this project would like to give an overview of whats
different?

Regards,
Rob.
