I have a rough idea of this, and indeed it doesn' seem very
practical (maybe the most ugly of all solutions ... ;-)

There is another implementation which is proprietary so I don't know
details, but most likely it uses an RD parser with some ad-hoc
special handling, both of which explains some problems it has in
other areas ...

OK. It seems most likely by now that there isn't any better solution
than the location abuse. At least, this is a very localized change,
so it will be easy to replace it in the future, if I get to know
about a better method ...
