Correct, there isn't one.

>Is there a way to define a global variable from within a function?

No, DSSSL is side-effect free, therefore there are no globals.

You can calculate and bind values to variables (a bit of a misnomer since
they can't vary!) within a given (let) scope, you can bind a fixed value to
a top level variable, but you can't change the value of a variable once bound.

If you want something calculated from the tree, you need to calculate it
within each element rule.

I hope this helps (even if it isn't the answer you were looking for).
