However, I would encourage use of key() rather than id(). Even in a DTD
world, id() is excessively dependent on how the stylesheet is run. For
example, some parsers (System.Xml is a notable example) do not notify the
ID-ness of attributes to the application, and inserting a filter between the
parser and the XSLT processor will often lose the information.

Cheers,
Wendell
