My point of view is, that envelope is just an envelope and shouldn’t be related to content.

If I want to send <iq type=„set” id=„1"> then I just send:

<message to=„X" >
  <encrypted xmlns=„…”>
    enc(<iq to=„X” type=„set” id=„1”></iq>)
  </encrypted>
</message>

and in response I will receive

<message from=„X" >
  <encrypted xmlns=„…”>
    enc(<iq from=„X” type=„result” id=„1”></iq>)
  </encrypted>
</message>


In case of using IQ envelope for IQ stanzas: what type of stanza should have envelope if response type is error? Also error?

<iq type=„error” from=„X” id=„1">
  <encrypted xmlns=„…”>
    enc(<iq type=„error” from=„X” id=„1"/>)
  <encrypted>
</iq>

I think that envelope should be independent from content. Let it be IQ stanza or Message stanza, but the same type of envelope for all type of contents.
