Yes, I understand that what I'm doing is rather a nasty mixing of
presentation and logic.  But, what I'm trying to do is gently ease some
zope3/five patterns into a plone/archetypes setting.  The zpt in question
is actually providing a custom 'view' for an archetypes object.  Thus, I'm
not sure how I could 'add a class to [my] template'.

It's just a standard zpt operating through a cmf/plone skin - so I guess
security is turned on ;-).

I wonder if I'm going about this the write way?  Essentially I'm trying to
get my standard zope2 zpt to behave like a 'view' I think - i.e. calling
logic code.  This has hack written all over it, but I don't know how else
to ease interfaces/adapters into an archetypes environment.

Any pointers much appreciated.
