Here are my two pence:

I'd like to also point out that the existing customisations and their generated
schemas available on the TEI website should be advertised more. There are
people who believe that to use P5 they *must* use Roma and ODD etc. rather than
just use one of the already available schemas. i.e.
[This just occurs to me at the point, since although we want them to have an
easy way to generation ODDs and schemas, we also want them to know that they
don't *have* to if they want to take the full tei or aren't interested in extra
constraints, lowering the barriers to use, etc.]

Agreed. One of the prime concerns is whether any of the suggestions on the
table for 1.1 would break backwards compatibility. If they do, and are deemed
important enough they should be moved up to essential for 1.0.

While final responsibility should lie with the editors, I feel that the council
should be helping at least in the areas of proofreading, checking clarity of

I feel that one should be allowed to create an ODD that won't produce a valid
schema, but whatever tools used to generate the schemas is where the validation
should generally be carried out. I.e. that web-Roma should allow one to create
an ODD that would produce an invalid schema, but that when it goes to generate
the schema, that its validity should be tested. But in generally I think this
issue is desirable rather than essential for 1.0.

Agreed. These should be essential. As TEI is making it easier and easier to
produce ODDs for TEI documents which increasingly differ from other TEI
documents I feel the community is going to worry about the increasing
fragmentation and dispersal of what they view as a TEI document. They like to
be able to conform to a standard, and funding bodies like the sound of that as
well. If one writes an ODD that completely renames and reshapes every TEI
element, and introduces lots of new ones, and ends up looking exactly like, say,
docbook, people are going to want to understand how that is still to be
considered a TEI document.

Is it likely that the changes Alan will want to make significantly break

I think that the material should be assessed, if possible, to see how
problematic it would be to make it compatible with the rest of the Guidelines.
Especially if the changes suggested break backwards compatibility if delayed

I would like to see listPerson, person, etc. in P5 1.0, and think that the
writing of related prose and reviewing of it should be given a higher priority.
I do not think, at this time, we should worry about necessarily getting
listPlace, place, or whatever into 1.0, and that this will wait just fine until 1.1.

I can't remember why we wanted it revised either. Was it to indicate the
relationship between app and choice?

I agree that this is desirable but not a block for 1.0.

I think this should be more than desirable, but essential. Overlapping
hierarchies has been such a hot topic over the last few years. And I've
encountered people mistakenly avoiding using XML because of their perceived need
for multiple hierarchies. (In most cases this has been more a result of
ignorance...) So my reasons for wanting this in 1.0 is less to do with
technical realities, but more to do with the perception of the TEI as solving
these problems as a community-led standard.

Essential? Would this break backwards compatibility in 1.1?

I think it should be global under the text element, and only selectively
available in the header. I think this change (or something like it) should be
essential for 1.0 as a reaction to the community's support of it. Another
option is to have note as a general element, but produce specialised syntactic
sugar versions of this for use in certain contexts. (But I'm not sure I think
that is a good idea.)

I think this is desirable, but as it might take awhile to get it right should be
slated for 1.1.

Desirable for 1.1.

In answer to your questions in that email (which I did comment on, albeit briefly):
1) I thought it was:
model.pPart.edit.choice = choice app
model.pPart.edit.transcribe = add damage del restore space unclear
model.pPart.edit.editorial = abbr corr expan orig reg sic supplied
and that .editorial should really be broken up so that you could use abbr/expan
in the reduced header phrase but not the others. I have no use case for using
choice inside header elements, and don't remember that really being the
suggestion. (But again, my memory is fuzzy).
2) Is it that the others are really more emph-like than hi-like? I can see
wanting to use foreign/gloss/term/etc in the reduced header phrase class, but
less so 'hi' (or distinct).
4) I think the argument was that code and ident are emph-like in many use cases.

Desirable for 1.1. Using persons isn't too much overhead if seriously needing this.
