XSL implicitly depends on a query language. It isn't defined separately
from XSL but it is defined in the XSL specification. That query language
actually has W3C standadization status and is needed for the Python XSL
implementation that is under development.

XQL is sort of like that language -- but not quite, and not standardized.
I think that before XQL becomes any kind of standard it would have to be
aligned with XSL's query language. Therefore you can choose yourself
whether you want to implement it in the meantime or not. It all depends on
whether you want to work on something that will likely be obsolete in a
year or not....in the XML world a year is a lifetime so maybe that's a
good tradeoff.
