I think we should discuss this on the standards list.
Contact me under the email address in my sig and i will send you test client
with our implementation.
It works like pandion and it works with the Soapbox server, which is the
correct way in my opinion.

> Hey guys,
> When implementing JEP-138: Stream compression my initially
> understanding was that <compressed> was being sent by the
> server once he was able to switch to compression mode and all
> validations have passed (e.g.
> compression is available, compression is not already in use, etc.).
> However, when testing against Pandion I found that Pandion
> was waiting for the <compressed> notification to be sent
> before compression is active.
> The reason for that is that the client was expecting a
> confirmation from the server saying that there was no
> <failure> and that compression can be established. And if a
> <failure> stanza was sent to the client then the client will
> still be able to parse it since compression is still not
> active. In other words, <compressed> is being used just like
> <proceed> in TLS.
> After chatting with Sebastiaan Deckers (author of Pandion) I

> Since we now have 2 servers and 1 confirmed client that are

> compression is active and after all validations have passed
