If these functions are only required by a specific template there is no 
need to add them to the global context. You can wrap the add form in a 
method and pass the functions (or better the result of the functions) as 
argument to the template. CMF's addConfiguredSiteForm does that e.g.:

http://svn.zope.org/CMF/trunk/CMFDefault/factory.py?rev=68622&view=auto


If the container allows to use views (by default that is not the case 
for generic Folders in Zope 2.9) there is a better solution: Use a Five 
view and add the functions to your view class. The ZCML version of 
registerClass allows to specify a Five view as add form.
