My point is that one of the reasons that the GPL was
popular is because it provided a key service and no
way to use it without linking. The open protocol
removes that, the linkage. The weakens the GPL to just
asking people not to use XML and other formats to
The GPL becomes a paper tiger, I am sorry to say.

I think it is commendable.

Ok, I had that feeling a while back when browsing he
available implementations and looking for one to try. 
Back then, one  GPLed dephi application had some
strange resizing problems... The number of commercial
implementations was quite high.

Of course that it the way to go for jabbber.

But if you wanted to provided a service to only GPLed
clients, there is no way to implement that under the
GPL. That limits the usage of any of the newer data
exchange protocols, even like jabber to the code GNU
tools. Each one can be abused via XML and linked to
without remorse.
