[Zope] tal:condition AND

[Mark Gibson]

Thanks for the suggestions.  With a little tweaking, I came up with 
the behavior I wanted.

tal:condition="python:path('hasThePermission') and path('request/date_edited | date_edited | nothing')

It does seem that since path has an 'or' operator, it should also have an 'and'
operator.
