thanks andy (and others) for the replies
I guess the best solution in the general case would be to store extra stuff
in javascript structures indexed by element ids. I hadn't really thought of
this.
in this case, I just want to store a single extra string value alongside
some of the <a> tags, so I will use my own custom attribute.
