<noah> I thought the ball was in my court to mark the product page approved

jt: Re fragids and mime types, I did a product page, needs to be revised per comments

jt: Re action 672, let's talk about that when it's done

nm: I will do a local arrangements page for the F2F

Regrets LM for 3rd day of F2F

<Ashok> +1

Vendor prefixes

lm: Because it was a narrow enough use case, and the community was making progress, this seemed interesting
... There are differences of opinion as to whether old stuff *should* go away ever [to force updates]
... The question is whether the CSS experience could apply in other situations
... Interesting proposal to put dates in vendor prefixes.

<Zakim> noah, you wanted to say that I think vendors are thinking in different terms

plinss: I don't think Apple has publicly said they're never going to drop things, seems flexible
... Mozilla, Opera have been aggressive about dropping prefixes

nm: We need to be realistic: a lot of what's going on here is the architects and those who deliver code to users are talking past each other. If a vendor-prefixed features is useful enough to get early adoption, then there will likely be market pressure not to drop it later. We've heard that "users" tend to disband or "defund" the teams that build these applications and move on to other things. Telling them to go back and update later is sometimes not practical.

lm: I think it's part of designing standards and extensibility regimes. It's important what vendors say, not just what they do.
... Authors aren't in the room, so we need to look for a trip point, and in this case it's the browsers

nm: But vendors can't predict how things will go, so won't want to make any promises. Users want to deploy quickly and then never rev

lm: I disagree. Don't think there's lock-in. There's no point in having a deployment plan unless people agree to abide by it

<noah> I do understand what you're saying. I'm just skeptical that vendors will do what you want them to do.

lm: I'm getting mixed messages. What you really want is that when a standard version comes a long, the prefixed version will go away. That means vendor needs to announce intent to remove nonstandard version, when standard arrives
... What I was hoping for was that at least some browsers would have some visual indication of obsolete or soon to be obsolete features

pl: Some of them do this in their developer views

<noah> The message I'm hearing is: many "customers" write their pages once, and then kill the funding or the teams that would be capable of rewriting them to change the spelling of things like CSS prefixes. The economic incentive for them to do that 2nd step isn't there.

nm: Look at how people fund these projects. Right now they use vendor prefixes. Then they move on. What I heard is that the team has disbanded by this time. So this would mean decisions not to use the features in the first place

lm: The use case was when there was a design team that wants continued work
... There has to be lead time, so people are prepared
... How can we strengthen the will to move on

nm: SOmething the TAG can do?

lm: Right now the deployment plans are locked inside places that are hard to find

nm: Peter, how is CSS working on this issue?

pl: We see most of the problem as education. Initiative to teach comes from the community, we try to correct them

<masinter> i thought we could document the issues around deployment plans, and point out best practices about how to design extensibility methods

<masinter> that's more general than CSS; we might look at why it is easier because of the "cascading" of style sheets

nm: So what can we do. Isn't CSS already doing a lot

pl: One way the TAG could help CSS is re proposal from Florian. I think his proposal would be harmful, and it would be useful if the TAG had an opinion on it

<masinter> TAG could evaluate Florian's proposal and other alternatives?

<masinter> if we worked on this, it should be rec-track

lm: Is this is the kind of thing we work on, we should get wide community approval, head for Rec track. But from a perspective that doesn't tie it to CSS
... Cascading makes this unique

<masinter> is this a lesson for XML-ER?

nm: We've tried to crack distributed extensibility nut many times. Agree that focus here is good. Feels like next step should come from CSS WG

<masinter> for example, if this extensibility method doesn't apply to XML, is there a refocus of XML dealing with un-recognized elements to make it more extensible?

nm: Worried about umpteenth frontal assault on issue

lm: Looking at specific cases is a good way to deal with general cases (Polya How to Solve It)

tbl: Not a good time for TAG to generalize, good to look at cases

<masinter> i'm a big fan of Polya -- here is a specific instance where a solution is tractable. The universal problem was too hard, but we might make progress on this one

nm: Should we do anything else re Florian's proposal?

<masinter> i think one of the big questions is whether "old stuff goes away" -- is it, or is it not, reasonable to assume that once a usage becomes significant it will never get dropped?

jt: Didn't PL just say it would be helpful for the TAG to evaluate Florian's proposal?

<masinter> i'd like to see the extensibility mechanism in CSS documented

<masinter> in a way that actually corresponds to what CSS WG thinks the policy is

lm: I'd like to see the CSS deployment policy to be written up, in one place. I don't think there is a document that describes the policy
... I'm reluctant to compare a proposal to the current policy, in the absence of a document describing the current policy

pl: It would be sensible for the WG to do this

lm: Peter, what do you want to do?

pl: I'm not necessarily endorsing the current policy, just wanting to comment on Florian's proposal

<noah> ACTION: Peter to report on CSS WG plans for documenting policies relating to deployment and withdrawal of vendor-prefixed identifiers - Due 2012-06-11 [recorded in http://www.w3.org/2012/05/24-tagmem-irc]

<trackbot> Created ACTION-711 - report on CSS WG plans for documenting policies relating to deployment and withdrawal of vendor-prefixed identifiers [on Peter Linss - due 2012-06-11].

<masinter> what input on I18N and normalization does the TAG want?

<masinter> this is on comparison & normalization?

lm: I'm interested & willing to talk about unicode normalization. Hard to tell whether this is about CSS selectors

pl: Selectors is just one of many places. Question is early, late, very late normalization

<masinter> i run into this with IRI docs

<masinter> if we're going to talk about unicode normalization, i'd want to cover IRIs too then

<Ashok> +1 to Larry

lm: If we're going to talk about unicode normalization, the IRI issues need to be in scope
... want to put the IRI comparison document in scope

nm: The action doesn't mention CSS, it's the I8n WG

lm: A month ago I18N WG committed to reviewing the IRI documents

nm: I just want to know if this is to be a F2F session

pl: Reluctant to ask them for a document without TAG commitment to work on this [?]
