[topicmapmail] Generating Bib-1/Z39.50 topics from instance metadata

[Kal Ahmed]

Hi Jason,

I imagine that you could do your referencing in this way. However, I also=
=20
imagine that many generic topic map browsers will display the reference=20
(probably as a link) and not the referenced content. As I don't think tha=
t=20
any web browser supports XPointer syntax yet, you may want to consider th=
is=20
problem if your target application platform is a browser.

Of course, if your target application is something you are writing and yo=
u can=20
bolt in the XPointer processing, then more power to you!

Cheers,

Kal
