topxml.com is wrong.  From the XPath recommendation:

   "The string function converts an object to a string as follows:

   A node-set is converted to a string by returning the string-value of the
   node in the node-set that is first in document order. If the node-set is
   empty, an empty string is returned.

   ...

   If the argument is omitted, it defaults to a node-set with the context
   node as its only member."
