See the section "What is Web Architecture?" in the TAG charter [1],
which starts:

   "For the purposes of this charter, Web architecture refers to the
    underlying principles that should be adhered to by all Web
    components, whether developed inside or outside W3C. The
    architecture captures principles that affect such things as
    understandability, interoperability, scalability, accessibility,
    and internationalization."

This paragraph was drafted by the W3C Advisory Board and reviewed
by the W3C Advisory Committee.

The TAG will publish one or more "Architecture Recommendations" by 
following the W3C Recommendation track. I am not aware of any 
particular format requirements or goals (other than clear English); 
some people may be interested in modeling the architecture using a 
formal semantic model, but that's extra credit as far as I'm concerned.

Between now and when the TAG advances Architecture documents
to last call, the TAG is publishing "findings" [0], which are
expressions of consensus within the TAG.

See the TAG charter [1] for more information about deliverables.

I do not understand this question.

There are documents that describe and define key pieces of Web 
architecture all over the place, including IETF specs and W3C 
Recommendations. The TAG was created to build consensus around
underlying principles. Those principles have been around for years,
and they have been discussed in many places. I am not aware of
a document or set of documents that cover the underlying principles
of the Web, that has been through wide community review and 
consensus-building. If there is, please point it out so we can all
go home! :)

See the TAG home page background section [2] for some suggested
reading.
