That's why I would like to be able to call macros (or named templates as
they are now called) from expressions...

If characters were nodes as they are in DSSSL then an "unmarked-up string"
would just be a nodelist. Counting characters would also become easy of
course.

Of course this is the right solution once official support is available.
I'm just trying to make a stop-gap.

First, are you talking about the current public draft or the current
internal draft.

Second, do you mean that the WD allows you to return nodesets from macros
(which I don't know how to do) or allows you to pass them in (which I do
know how to do). If so, then it would make sense to be able to call them
from expressions.
