Yes. The xml data access is through a stack-based progressive scanner
build on top of libxml.  Its overkill for out needs, it was 
really meant for xml-rpc-like parsing which is how we were going
to make QOF be network-distributed. 

We don't support mysql because mysql doesn't have the features
that we need.  

ODBC was designed by a moron who doesn't know C programming.
ODBC is a great example of how not to design an API.

libdbi.sourceforge.net is great for low-level bits-n-bytes access 
to sql db's.  Its easy-to-use, small, fast, well-designed.  
A great example of how to design a low-level API correctly.  

If libgda is using native postgres/mysql api's for its server
providers, you might want to look at using libdbi if you haven't 
done so.  It does everything the native libpg does, and it has 
drivers for other sql db's too.  I dunno, I have not really used
libdbi extensively yet, it may have faults I haven't discovered.
