Palm and docbook

I've recently bought a Palm, and find the Palmreader
docs quite readable.
   One app I've got has poor onboard docs, so I've offered
to re-write them in docbook....

Has anyone tried either..
docbook->plain text,
docbook->Palm palm markup language..

roughly a mix of \tex and xml from what I gather.

I've started (just) docbook, starting with html,
to pml.
Currently my main problem is giving up on links
which are extra-book, or at least recognising them.

E.g. the <link element in chunk-common.xsl
I'm a bit suspicious of this as being re-processed?
Is it, to generate <a href=   later on?

Anyone interested in Palm output?
