My cunning plan to get people's attention worked then :) We can work through the questions as part of the agenda item.

I'll send out an amended agenda with the liaison docs added.

Your agenda says: "Approval of....", hence my advance concern.  Plans are good.

Re Proposal #2 (in addition to the AI I thought Glenn still had about flow):

Although there was email discussion about them being anonymous regions, how is that inferred from the proposal language? Even if it is normatively inferred, it might be good to informatively note that explicitly as it is crucial to understanding the basic behavior.

What styles do they inherit?  I think the styles would need to be inherited from the "current" region, not the styles from the near-proximity parent elements.  More on this and other things in the attached email from last summer, which I don't recall resolution on.

Unrelated, can we add an agenda item to accept the old liaison requests from SMPTE and thus enable work on specific proposals?

Yes CP5 is not up for approval at this time, I only wrote it today as per my AI form last week; so I'll just be going over whats there.

CP 1 & 2 have been out there for a long time and no discussion, so we need to make progress on them it's not so much that I expect to approve them this week, although that would be nice, but more that I want to know specifically what the action plan is for doing so.

As to the defined behavior, I believe the mapping is well defined to intermediate anonymous region, so that the text flow issues are as well defined as text flows are in any region however I will go back and check that in advance of the discussion tomorrow.

Some advance thoughts:

1. Proposal 1 (extension to set) is OK with me.

2. Proposal 2 (origin and extent semantics for <p>) - although I am cautiously supportive of exploring this, I thought we previously agreed that it is still lacking defined behavior for how text would flow within the region, including wrap behavior, as well as the behavior of CR, LF and TAB when content is randomly placed like this.  I think flow examples would be needed just to better understand the ramifications, as this will be complex.
An alternative might be to define a non-flow region? (Just an idea - the use cases that this addresses do not generally involve "rollup" captions).  A minor comment on the first bullet of the "Impact" - the fact that there are attributes that have no semantic meaning on some elements is a very general issue and therefore the fact that the XML schema (properly) represents the permitted syntaxes on <p> is not really relevant or specific to the affected element and attributes. Suggest it be deleted. 

3. Proposal 5 - Although we discussed this generally, I don't recall seeing these details before. I'm not opposed, but it seems like it would be premature to approve it tomorrow.

Regards,

	Mike
