Have a look at zope/pagetemplate/readme.txt - it shows (one way) how to
inject 'order' into the tal 'namespace'., e.g.

>>> class MyPageTemplateFile(PageTemplateFile):
...   def pt_getContext(self, args=(), options={}, **kw):
...     rval = PageTemplateFile.pt_getContext(self, args=args)
...     options.update(rval)
...     return options

>>> orderform=MyPageTemplateFile('orderform.pt')
>>> orderform(order=OrderView())
