Thanks for the exhaustive search!

These link against the C library libxml2, doesn't use lxml.

Yes, its bundled. Hard to see how/if it uses it since a lot of source
code is missing.

This only uses lxml for displaying descriptions, and already copes if
its not installed (no descriptions shown).
It could instead use BeautifulSoup for HTML parsing - this is nicer
(IMO) and is not going away any time soon.

If it's a binary its not an issue. Only python code will be affected here.

Will need updating to latest Read code anyway to continue working on F17.


So I'm still feeling comfortable about dropping lxml and will probably
do so soon.
