[xml] python hash code suggestions for libxslt types

[Nic James Ferrier <nferrier tapsellferrier co uk>]

I find I want to store stylesheets and transformation-contexts in a
python hash table (for asynchronous retrieval).

Neither stylesheet not transformCtxt has a hash function
implementation.

It's difficult to think of what to return for a hash code.

Can anyone make a suggestion?
