- "On the web" is not defined in this document.  I would think that we would
want to define what "on the web" means for V1 of the Web architecture.  My
stab <shields mode="up">"On the Web means that a URI may be dereferenced
without the input of a representation, typically a GET retrieval.  Being on
the Web versus not on the Web is a trade-off in properties achieved and is
not be default a "bad" thing.  Some Web resources necessarily must be off
the Web, such as HTML FORM POST results." </shields>

Section 3. Representation

This section should contain a definition of a "message", and explain the
relationship between message, representation, representation metadata, and
other metadata.  "message" is mentioned in bullet 2.

I believe the last sentence in the 2nd bullet is slightly incorrect.  "When
transferred by a Web protocol, a representation often includes metadata
about both the representation and the message bearing the representation
(for example, some HTTP headers). "
"When transferred by a Web protocol, a message often includes metadata about
any contained representation and the message itself (for example, some HTTP
headers). ".

representations don't include message metadata, the messages include the
message metadata.

A diagram would be really good for this, ie:
Message is:
||metadata      ||

"Authors and applications can use URIs uniformly to identify different
resources on the Web" -> "Authors and applications can use URIs uniformly to
identify different resources".

"The simplest way to achieve this is for the namespace name to be an HTTP
URI which may be dereferenced to access this material. The resource
identified by such a URI is called a "namespace document."  ->
"The simplest way to achieve this is to provide a resource, called a
"namespace document", that is identified by a dereferencable URI."
