Ah. I don't know these well enough to say that they work or not with the 
Zope2 templates, so we'll assume they don't. (Pages and menus get named 
@@something, and that works, but otherwise I don't know.)

OK.

Because then, Five/CMF products can not use schemas and widgets, since 
they are in Zope3 templates. There really is no way around it. All pages 
must be of the same flavour. Being able to use Zope2 PageTemplates 
solved so many issues, that I'm not willing to drop it unless a new 
issue turns up that makes that solution unusable. You obviously (and 
quite reasonably) will not drop Zope 3 templates. I see no other 
solution than a config-statement so select which is to be used for the 
page-directive, if we are to continue to use the same codebase.

Then, if you want, we can have a page2 and page3 directive as well, but 
I really don't see the point of it.

Having a configuration statement is explicit.
