It's the same type of thing. 14:08:53 Norm: I think you're right. 14:09:23 ...I think for p:catch, we should just remove the word "output" which I think was Mohamed's suggestion. 14:09:38 Vojtech: It occurs in two places. 14:09:58 Proposal: Remove "output" from the discussion of the error port where it's an input not an output 14:10:00 Accepted. 14:10:22 ACTION: Norm to write an erratum for the incorrect description of "error" as an output port in p:catch 14:10:54 Topic: Review of state of processor profiles work 14:11:22 Henry: I've made no progress yet, hope to have something ready for next week. 14:11:50 Norm: Alex looked at xml:id and XInclude 14:11:51 -> http://lists.w3.org/Archives/Public/public-xml-processing-model-wg/2011Jun/0007.html 14:12:24 Alex; Yes. I was able to get xml:id working quite well. It relies on DOM mutation events which work successfully in browsers where its supported. 14:12:43 ...Unfortunately, webkit browsers don't support the mutation events API. 14:13:03 ...That's related to XInclude because it talks about maintaining references. 14:13:28 ...XInclude itself also works quite well, with the exception that the base URI property isn't used properly in some browsers. But that's just a bug. 14:13:56 ...If you programmatically change the base URI by adding/changing the xml:base attribute, that has no effect in some browsers. But it does work in Firefox. 14:14:24 ...Long story short: you can implement it in JavaScript. But if you have an implementation of this, then how does it get invoked? 14:15:01 ...In some browsers, if you put XHTML script tags in, those scripts run. But in other browsers, e.g. IE9, then they don't. So there's no universal way to start the process. 14:15:17 ...It might be possible to do this with extensions, but that's not standard browser behavior. 14:15:43 -> http://lists.w3.org/Archives/Public/public-xml-processing-model-wg/2011Jun/0009.html 14:16:19 Alex: Is there anything to note about this in the spec? It should be said that xml:base is supposed to change the base URI. 14:17:06 Norm: Is it worth adding to the spec? 14:17:12 http://www.w3.org/Bugs/Public/show_bug.cgi?id=12924 14:17:48 Alex: The browsers do support xml:base, and HTML5 describes the right behavior, but it's not clear what happens when you programmatically change the base URI. 14:18:33 ...You actually have to find and re-resolve the URIs on the elements. 14:19:06 Murray: Are you suggesting that if you didn't rely on base URIs, that is if you provide the fully qualified URIs, that generally the browsers do what they need to do except for recursive XIncludes? 14:19:40 Alex: No. I'm saying that Firefox does the right thing. The other browsers I tested don't do the right thing. But that's a bug and I've filed them. 14:20:05 ...And the HTML5 spec says that what Firefox is doing is the right thing. 14:20:43 ...What's not supported is programmatically changing the base URI to effect descendent attributes. For example, after an img src has been resolved, changing the base URI on an ancestor won't cause the img src to be recomputed. 14:21:26 Murray: Are there utilities for doing base URI resolution? Like a unix filter that will expand URIs and give you back the fully qualified URIs? 14:21:59 Alex: You could *write* one. There isn't a standard API in the browser to do this. 14:22:11 Norm: XProc has a step to do this. 14:23:03 Alex: Because we have the base URI property, we can control it. What the host language does is up to them and should be made clear. 14:23:22 ...We should make it clear that the right semantic is that you resolve the URI against the base URI of the element and xml:base controls that. 14:23:28 ...There's no magic. 14:23:34 ...That's pretty much what the HTML5 spec says. 14:24:55 Further discussion of the behavior of the base URI 14:32:28 Some discussion of what it means, or should mean, to change the xml:base value after a document is ... yeah, is what? parsed? rendered? 14:34:48 ACTION: Paul to put the discussion of dynamic changes to xml:base on the XML Core agenda 14:38:43 Topic: Transclusion in HTML5 14:39:38 Henry: This was background to Alex's concern in this area. Coming from a completely different perspective, the members of the team were saying that they need XInclude functionality without knowing it. 14:39:42 ...It was really just as background. 14:40:00 ...We'd had this discussion of whether XInclude should be int he profile we're hoping to sell to the browsers. 14:40:51 Murray: Years ago, I imagined a world where you could use entities to pass along secret messages. No one would rely in them so they wouldn't show up in most tools. 14:41:29 ...But every now and then someone would read a document that used an entity to include a secret message. 14:41:35 ...That's why I'd like to say something about these things in XProc. 14:41:59 ...We need transclusion, we've always needed it. That's why we had entities in SGML. That's why Ted Nelson coined the term. 14:43:22 Some discussion of the future of entities. 14:44:37 Murray: The case that I care about from GRDDL wasn't handled because we didnt have XInclude in our profile. 14:44:44 Alex: That's true, that's part of the reason we got here. 14:46:16 Norm: I think we're trying to get there. Can we get the browsers to support XInclude, can we do it in JavaScript if it's not part of what the browse does by default? 14:46:30 ...These are the sorts of questions we're trying to resolve. 14:46:39 Alex: It's clear that entities are dead in the browser. 14:50:00 More discussion about profiles in general and support for GRDDL 14:51:22 ACTION: Norm to include an explicit mention of satisfying the GRDDL faithful rendition property in the appropriate profile 14:51:29 Implementing GRDDL in XProc: https://community.emc.com/docs/DOC-10276 14:52:36 Topic: Any other business? 14:53:40 None heard. 14:55:35 Some discussion of f2f meetings: TPAC is it for this year 14:55:40 Adjourned. 14:55:41 -Murray_Maloney 14:55:45 -Vojtech 14:55:46 -Norm 14:55:46 -PGrosso 14:55:48 -alexmilowski 14:55:49 rrsagent, set logs world visible 14:55:49 -ht 14:55:49 XML_PMWG()10:00AM has ended 14:55:50 Attendees were Norm, alexmilowski, Vojtech, PGrosso, ht, Murray_Maloney 14:55:54 rrsagent, draft minutes 14:55:54 I have made the request to generate http://www.w3.org/2011/06/09-xproc-minutes.html Norm 14:56:07 PGrosso has left #xproc 16:12:59 Zakim has left #xproc 17:27:11 ht has joined #xproc 18:39:12 ht has joined #xproc 20:31:07 ht has joined #xproc 20:39:40 Norm has joined #xproc 21:01:20 ht has joined #xproc
