The nice thing here is that Collections are optional in XMLDB Core 0. 
You can get away without them initially and just treat the container as 
one common collection.

An initial implementation as one common collection avoids this until a 
collection strategy can be designed/developed.

Yes, and later, if further collection information can be aggregated in 
the metadata of a Resource, theres possibly a means to approach the idea 
of the collection through some sort of merging of XQueries against that 
metadata information. However, if there were a means to reorganize the 
structure of BDBXML so that it supported Collection hierarchies 
intrinsically in the organization of its datastore, then that would be a 
very powerful feature thats already present in many Native XML 
databases, sounds like something that I would want in BDBXML as a 
feature even at the level of the BDBXML api.

RHEL, Fedora, rpm packaging would be great to have on these systems.
