[Zope3-checkins] CVS: Zope3/src/zope/configuration - fields.py:1.13

[Stephan Richter]

Update of /cvs-repository/Zope3/src/zope/configuration
In directory cvs.zope.org:/tmp/cvs-serv30443/configuration

Modified Files:
	fields.py 
Log Message:
Implemented new syntax for assigning "explicit" Message IDs in ZCML. 

The Syntax:

<.... attr="[MessageID] Default Text" />

<... attr="[] [Escaped] Default Text" />

While other solutions were proposed, this one was the only one that would 
not require a total rethinking/rewrite of the ZCML internals (and we just
has a ZCMLgeddon, so I think it will not happen soon again. ;-)
