>From the XSLT 1.0 spec (http://www.w3.org/TR/xslt#misc-func):

"An implementation is under no obligation to generate the same identifiers
each time a document is transformed. There is no guarantee that a generated
unique identifier will be distinct from any unique IDs specified in the
source document."

A more stable unique key generation is to use the XPath expression that
selects exactly the node, concatenated with the URI of the xml document.
