[Zope] Acquisition from a DTML method in a subdirectory

[Troy Farrell]

The short reason that this works is that using expr="some_method()" calls that 
method without passing the namespace to it.  The underscore variable ("_") is 
the namespace variable (or something like that.)  If you don't use expr="", you 
can use name="" naming the function without () to accomplish the same thing. 
Note that you cannot (to my knowledge) do name="B.Bdtml_method" because the "B." 
portion of that is an expression, hence Chris mentionning <dtml-with B>
