The xml provider is the old 2.2 backend, and should always be present, and 
should be registered as both "xml" and "file".  At startup time, the dbi 
backend looks to see what drivers are available, and registers 
"sqlite3"/"file", "mysql" and "pgsql".  The sqlite3 backend is registered as 
both "sqlite3" and "file", and if "file" is used (or is omitted), the sqlite3 
backend checks out the file, and if it fails, the xml backend tries.  Default 
for loading is "file", and for saving is "sqlite3".  If "sqlite3" is not 
available (hmmm - I may not handle that case), "xml" should be the default for 
saving.

I tested without the mysql and pgsql drivers.  I didn't test without the 
sqlite3 driver.  I'll do that.
