'provider' TALES expression are not registered for Z3 page templates

[Godefroid Chapelle]

Even though Z2ProviderExpression (which provides 'provider' expressions ;-)
is registered in the TALES engine of Products.PageTemplates,
the 'provider' expressions are not available for the pure Z3 page templates
from zope.pagetemplate or zope.app.pagetemplate.

To fix this,

just add Products.Five.provider.zcml (attached)

and add the corresponding include in Products.Five.configure.zcml :

  <include file="provider.zcml"/>

I can make the work in trunk and back port to 2.10 and 2.11 once I get the 'go' from the release manager.

2.11/trunk should be no problem.
Does the patch solve any particular major issue we're having with 2.10?
I don't see any major risk adding it to the 2.10 branch as well. Looks like
an oversight. So go ahead.

No major issue, but allows to use z3c.form more smoothly.

That's what I thought.

@Gotcha: did commit the change?

[Godefroid Chapelle (gotcha)]

Oops, that went out of my radar.

Ill try to make it this week !

zope.pagetemplate files aren't usable directly in Zope2. There's a number of differences, most notably the different engines and context implementations. Simple configuring one expression type in the "Zope3" engine isn't of much use - we would have to configure the entire "Zope3" engine.
