As for the technique, I've used it (though not this precise code) on one-or-another SVG-generating stylesheet. It works fine in Saxon. :-)

Both answers are not completely correct:
-- Wendell's because he hasn't converted the RTF into a node-set before applying the string-length() function on it.
XSLT 11.1:
"A variable may be bound to a result tree fragment instead of one of the four basic XPath data-types.... A result tree fragment is treated equivalently to a node-set that contains just a single root node. However, the operations permitted on a result tree fragment are a subset of those permitted on a node-set. An operation is permitted on a result tree fragment only if that operation would be permitted on a string.... When a permitted operation is performed on a result tree fragment, it is performed exactly as it would be on the equivalent node-set."
-- Mike's, because the variable contains not a (flat) node-set, but a whole tree.
...which you can't query into (its being an RTF), but which you can get the length of (since it can be operated on as if node-set converted to a string).
