<RT> IMHO, for the requirements document, talking about requests and
responses
<RT> at this level is too detailed. I thought the requirements document
just
<RT> specifies printing problems to be solved from a layman's
perspective?

<RT> Can we just say that finding or locating a printer would primarily
<RT> be accomplished through a directory-service enabled client? I think
<RT> this is the only mechanism we have talked about for dynamically
<RT> discovering the existence of IPP services within a particular
<RT> domain.

<RT> IMHO, this should not be a requirement. Its a possible
implementation, but
<RT> should not be a requirement

<RT> I agree with Roger. For the requirements document, we should
probably
<RT> just say that support for asynchronous notification of job status
will
<RT> be supported; any details with regards to how its supported would
be
<RT> in a separate protocol section, chapter, or document.

<RT> I agree with everything Roger said. Ditto.
