[Zope] calling product ZClass add method

[Chris Walter]

Hi Everyone,

Can anyone tell me how I can create a ZClass instance via DTML from
outside of the product directory?  Using the add new item button at
the bottom of the page in a folder works fine but I also want to
create some instances dynamically in DTML. I can't figure out how to
call:

manage_addProduct/photoCD/multiRes_add

using the <dtml-call X> sequence.  multiRes is a ZClass in the photoCD 
product directory.
