Yes, its great to see this submitted and published. Personally its been a bit of a nerve wracking wait to get the submission (and the submitters) lined up, for each organization to make the requisite Royalty Free commitment, and to then get the Submission accepted.

A somewhat arcane aspect of W3C process is that, in between a submission being sent to W3C and the decision to publish it (or reject it or to send it to a WG without publication) the submission can't be discussed in public. 

There are good reasons for this, mainly to cover the case where a WG has a particular direction and some W3C Member wants to make it go off a different way and (mis)uses the Submission process to do so rather than making the proposal in a WG and using the consensus approach. That is not at all the case here, the submission is exactly what we wanted to work on, but the rules still applied.

I'm glad that the "know but can't tell" part is now over.

Yes. The current charter has a single format deliverable, WOFF, while the draft charter had two,  CWT (EOT Lite) and WOFF; and the uncomfortable partitioning of the supporters of those two - basically "Microsoft" and "everyone but Microsoft" respectively. As several people pointed out, that was a recipie for a standoff in the WG and for confusion and uncertainty in the typography and web design communities.

I was pleased when discussions allowed the charter to be streamlined to just WOFF, shortly before the charter went to the W3C Advisory Council (AC) for review. That increased the chance of success greatly. And I was pleased when that shift of support at Microsoft also manifested as an interest in being a co-submitter of WOFF. Naturally the legal review required gave some additional delay, but that was I think well worth it.

The Submission sends a strong signal of political will to work together, which is valuable.

We may still get a member or two, but there is no reason for delay now that we have the WOFF spec.

I would like to see us walk through the spec, as a group. Either in email or on a call. Partly to ensure we are all up to speed, partly to look for ambiguous wording, and partly to look for missing, essential features if there are any.

I would certainly like to see some examples of metadata statements. We could collect these on the wiki, for example. Its much easier to copy an example; good examples help adoption.

Yes, we need to decide that.

In my opinion, regardless of where that aspect of conformance goes, it should not be optional. Same-origin (as a default, with CORS to relax it) only really works if its required.

LV> 3) Develop Web Font conformance spec (see details in the WG charter [1])

We will probably need both sorts of test.

Automated tests, whether they use the DOM or use XSLT or whatever, comparing some output to the desired output, are great because there can be a lot of them and they can be run frequently without requiring much human time; excellent for creating an implementation test report and for checking an evolving implementation for regressions.

Some tests are hard to automate, either because they require human interaction or because the conformance requirements are complex and hard to express in a machine-discoverable way. We should not shy away from such tests, but in my view we should prefer automatable ones where possible.

I agree that we are in good shape for implementation experience at this early stage, but we should not rest on our laurels here.

For now I think its sufficient to maintain a list of known implementation (I will do that) and to continue to build contacts with those development teams. In my experience, good contacts really help in terms of bug reporting and fixing in response to changes in the test suite, for example. Its also a form of outreach, and good contact with the developer community is part of our charter.
