Re: How can I bend generate-id()?

First let me apologize to those whose email rendered the included HTML
output. I wasn't thinking and I hope it has not inconvenienced anyone
terribly.

Second, in the words of Gilda Radner as Emily Letella, "Never mind."
I was able to solve the problem with twelve keystrokes and the realization
that my template would only output a maximum of three nodes for each
input node, and I know in advance which kind they might be, so I simply
appended a dash and a three-letter code to the return value of generate-id().
That way, even though the output of generate-id() doesn't change with
multiple calls from the same context node, the value stored in the each
element's id attribute will be unique.
