Subject Re: WSS-148 WCF interop issue: Namespace not honored incase of attributes.
Date Mon, 01 Jun 2009 14:12:05 GMT
Actually, it was George who pointed out to me that the qualified and
unqualified forms are different as far as XML is concerned.

I think ideally, WSS4J would need to be configurable by the service provider
as to what should happen when the wsse:Type attribute is present.  If you
don't need/want to accommodate VS 2008/WCF clients then the current
behaviour is correct.  However, from a practical point of view, it would be
nice to be able to configure WSS4J to accept wsse:Type when Type is absent.
Naturally, this would imply that there couldn't be application specific
semantics to a wsse:Type attribute.

Perhaps it would make sense to implement this as a distinct
UsernameTokenProcessor so as to not contaminate the current one with
deviations from the spec?

I wouldn't expect the default behaviour to accept wsse:Type, but a simple
FAQ entry could refer to this other UsernameTokenProcessor and point people
to the appropriate place to bug MS to fix WCF.
