Hi, we are upgrading a customers project from Zope 2.11.x to Zope 2.13.4. In this project the expression type "provider" of zope.contenttype is used. But loading the configure.zcml of zope.contentprovider fails with: ConfigurationError: ('Unknown directive', u'http://namespaces.zope.org/tales', u'expressiontype') I tracked this down to Zope2/App/exclude.zcml where the meta.zcml of the package zope.browserpage gets excluded. Sadly this ZCML file defines the expressiontype directive. What is the current way to use zope.contentprovider in a Zope2 environment? I had the following idea to fix this issue: * move the registration of the directive from meta.zcml into meta-expressiontype.zcml * include meta-expressiontype.zcml of zope.browserpage * include meta-expressiontype.zcml in our project to get around the exclusion of Zope2 Are there any better ideas?
