From a processing point of view, the message is discarded (i.e. not

It's interesting, because the current the current text[1] refers to
the section of SOAP faults as a reference to "discard":

  It MUST discard messages that have incorrect namespace information
  (see 4.4 SOAP Fault)

Maybe the spec should say:

  It MUST not process messages that have incorrect namespace
  information (see 4.1.2 Envelope Versioning Model).

'incorrect' looks good to me: in the context of the SOAP Version 1.2
specification, only one namespace URI is recognized and considered
correct for the envelope (<> as
currently in the draft).

I agree with you, but I seem to remember some earlier discussion
during which we decided to allow this; I can't remember when and why
though, so it might just be the fruit of my imagination.
