Subject Re: Extension Factories and Namespaces
Date Wed, 12 Jul 2006 01:46:36 GMT
I'd say go for it.  If you note, I had already take the step of adding a
method to the extension factory to determine whether or not it is
capable of handling a particular namespace.  This shouldn't be that big
of a change to make.
