XSL as a DB query language

Do you think that XSL could really be used as a generic XML Repository
Query Language ?

What would the more evident limitations be ?

Is there any alternative (for example: SQL or OQL extensions, XPointer,
etc) ?

And are you aware of any existing prototype of an XSL query engine ?

Thanks in advance.

P.S.
An aside question: are you aware of any good XML data repository
technology ?
I was able to find only the ObjectStore and Poet offerings, I guess that
there should be something more, especially in the field of SQL
databases.
