I haven't verified that one either way... 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."
