yes but as in most languages, variables hold values not fragments of
language syntax. In C (or java or ...) you can't put part of an
expression like " + 1" into a string variable x and then just use
1 x
to have it evaluate to 2.


is legal syntax but as the expression  $toLang doesn't depend on teh
context node it just produces a sequence of multiple copies of $toLang
as many  as there are nodes in document('')/*/trans:tr/tr_string[@str=$str]
