actually has anyone done any timings comparing handling inherited
attribute values via ancestestor-or-self::*/@xxx rather than
saving the value "on the way down" and using parameters to pass the
information to templates handling the descendent nodes.

Unlike // which potentially causes a search of the whole document
I'd have thought that for most document types the number of ancestor
nodes is typically quite small, and so looking back up the ancestor axis
to find the relevant xml:lang should be quite efficient?
