[Zope3-checkins] CVS: Zope3/src/zope/app/xml - meta.zcml:1.1 metaconfigure.py:1.1

[Philipp von Weitershausen]

Update of /cvs-repository/Zope3/src/zope/app/xml
In directory cvs.zope.org:/tmp/cvs-serv3948/xml

Added Files:
	meta.zcml metaconfigure.py 
Log Message:
* introduced IXMLRepresentable interface for objects representing xml.

* introduced a new ZCML directive to register XML Schemas as interfaces
  by specifying their URI.

* changed the way interfaces are resolved in all configuration directives
  and some other places. Thus, you can now also specify the URI of an
  XML schema instead of a dotted interface name everywhere you are required
  to specify an interface name.
