Re: generate-id() explanation

A small warning:

Do not use generate-id() to produce links that users may bookmark
and/or share with other users.

The next time you generate your HTML document by applying again the
same transformation, the values produced by generate-id() for the same
nodes may be quite different from the values produced on the previous
transformation -- even if the source XML document and the
transformation are identical to what they were on the previous
processing.

To quote the spec:

"An implementation is under no obligation to generate the same
identifiers each time a document is transformed."
