You're getting a Result Tree Fragment assigned to the variable because 
that's what you're building by calling a template. Unfortunately, the only 
way to get another type assigned to a variable is with the select 
attribute, which won't work if you need to call out like that.

Fortunately, the remedy is easy enough. Cast the RTF to a number by using 
the number() function when you test it, as in test="number($top-remove)". 
It will then be made into a number (NaN if its string value doesn't 
represent a number), and will test Boolean-wise the way you want it.

Good luck,
Wendell
