  Please don't do that!  This is an example of the more easy
to write, difficult to track bug in XSLT 1.0.  Your XPath
expression select a node-set with several nodes, and you
silently reduce that node-set to its single first node (with
string() called through number()).

  If you really want to get only the first node of that
node-set, just write it explicitely in your XPath
expression.
