No new normative requirements. But also no old normative requirements,
as far as I can see. [But see below.] As result, there will be nil -
zero - normative requirements - apart from WCAG [which already
applies]: No normative alt authoring requirements in HTML5 proper, none
in the alt techniques document - and none anywhere else.
We have a focus on whether conformance checkers should be allowed to
drop conformance checking of the @alt usage when the META Generator
element occurs in the document. But we won't have @alt text validation
if there is not going to be any normative authoring requirements.
See below.

My advice is to drop this CP and instead use the energy to focus on the
remaining IMG related issues we have, including @longdesc.
But if you insist on continuing with it, then update the CP with the
following info:
* Explain the precise fate of the @ALT techniques document:
- Its [new] title
- A list of the formats it will cover [Word, ODF, SVG, HTML, etc]
- Who is to be responsible for it - which WG
- Whether it is to be considered one of the many WCAG _techniques_.
That is to say: Will it be a single technique document. Or will
the document's many sections become independent technique documents.
- How it differs or not differs from other WCAG technique documents
and whether it will replace any existing WCAG technique documents
and whether it will be authored in a way that differs from other
WCAG technique documents
- if @longdesc gets included in HTML5, will its usage be described
in this document?
- other relevant things
* Explain consequences for - and relationship to - the HTML5 spec
- The [possible] consequences for HTML5's section on
'Guidance for conformance checkers' [1]
- whether you'll reuse *anything* of what your want to delete
from HTML5 or whether you will start from scratch
- how will you [not] be bound by the HTMLwg's [old] @alt
related decisions
- whether this CP will put to rest the current IMG related
issues, such as the Generator exception and the @title usage issue.
This may be seen as an extension to previous point:
* Describe the consequences for conformance checking of @alt.
- will there be any @alt checking in HTML5-conformances checkers
or will such things be moved to a specialized checker.
If there will be any kind of HTML5-conformance @alt checking, then:
- what kind of checks HTML5-conformance checkers be required/asked
to perform? E.g. will it be exactly like in HTMl4? Or will
there be no requirement to check, but instead an encouragement
to check - some things?
- on which basis HTML5-conformance checkers will perform such
checking - where are the requirement to be fulfilled described.
- Currently, some @alt mistakes constitute Errors. It seems like
this [possible] new approach could only allow trigger Warnings.
Please explain.
PS: I also encourage you to have much shorter and more precise Summary.
Currently, I had to read as far as to the Details section, in order to
start to get an overview of what it suggests.
