Thanks, that explains it quite well.

Except.... I modified my script to produce the output exactly as you
and the document suggested. I put that on the server, and then read
the source to verified that it got there. And the W3C's link checker
still says it's broken. Caching issue?

To test that theory I installed it locally ("aptitude install
w3c-linkchecker"), and ran that. The local version reports no broken
fragment errors.

Curiouser and curiouser, as Alice would say.
