[Zope3-checkins] CVS: Zope3/src/zope/app/interfaces/container - __init__.py:1.11

[Steve Alexander]

Update of /cvs-repository/Zope3/src/zope/app/interfaces/container
In directory cvs.zope.org:/tmp/cvs-serv22217/src/zope/app/interfaces/container

Modified Files:
	__init__.py 
Log Message:
Made ContainerSized depend on IReadContainer not IContainer.

Made ZopeItemWriteContainerDecorator, and IItemWriteContainer and
IZopeItemWriteContainer interfaces to express the dependency that
writing to a ZopeContainer has on IItemContainer.

Added zcml to make these different kinds of decorators work.
