According to my findings, the provider-expression should work in Zope2
PageTemplates (Products.PageTemplates) as it is registered in
Products.PageTemplates.Expressions.createZopeEngine.
In the project mentioned before Zope3 PageTemplates (zope.pagetemplate and
z3c.template) are used, too.
Sometimes we had permission problems ("UnauthorizedBinding: context") with the
Zope2 PageTemplates even with Zope 2.11.
Maybe mixing Zope2 and Zope3 PageTemplates is the source of the permission
problems.
As the outermost template is a z3c.template I doubt fixing the expressiontype
declaration will help much in our use case.
It will help to get zope.contentprovider running in Zope2 as this package has
no reference to a TALES-Engine, everything is done in tales:expressiontype.
Yours sincerely,
