I don't think anybody is suggesting that it should be dealt with as part
of XML protocol (i.e. be defined by this WG). However, there are many
reasons why people might want to provide XP modules that describe
authentication etc. - to name a few:

* people can obtain a much finer control within the XP message
  than for security outside which can only apply to the message
  as a whole.

* people might not want to rely on mechanisms defined for 
  specific protocol bindings

* people might want to use intermediaries to perform specific
  tasks which then have to be described in terms of the XP
  envelope.

I have tried to illustrate the relationship between XP and XP modules in:
