Hi Alexis,

Thanks for posting this. I think this is an important topic.

At present it's a bit unclear to me what this document is proposing, so I'm
not sure whether I agree. It seems to me that there are two types of things
that
need to be specified:

- The input syntax that goes into RFCXML
- The output format that is going to be produced

It seems like this document outsources decisions about the second of these
to the RPC and doesn't say much about the first at all. As an author,
however,
a lot of my concerns are about being able to write documents with math in
them, so I think we do need to specify some sensible thing that xml2rfc
will accept, as long as that remains our common input format [0].

Accordingly, I think we need to add something like:

The RPC shall define an input format for mathematical notation and
requirements for enhancing xml2rfc to translate that input format into
the output format defined in Section XYZ. That input format shall be
based on pre-existing defined mathematical notation input formats.

-Ekr

[0] Recognizing here that there are questions about whether the same format
should be used for draft authoring as for RFC publication.
