Direct Access to eXist

I posted a suggestion on the eXist mailing list to
their discussion about directly integrating eXist with
XSLT.

The response was that serializing the query results
was too much overhead.

I suppose the answer is "no," (and its certainly in the
code for me to discover) but I wondered if indeed there
was a way to pass the eXist query result tree directly
to Orbeon?

Serializing to a tree is generally a lot of overhead. Doesn't Orbeon
operate with SAX sources and SAX results? What you need is a SAX
serializer for eXist, if there isn't one there already...I seem to
remember (in the distant past) making some modifications to an eXist
serializer so that it would directly drive a SAX source...

I think we had a discussion on the topic of SAX recently:

Currently the most powerful way to use eXist's REST interface is from  
XForms, which deals with trees. In most cases, stuff ends up in a tree  
so you can do something useful with it. There are exceptions of  
course, so it's good to stream whenever you can, and try to avoid  
creating/serializing intermediary trees.
