(taking comments one by one)

ED: is it good to collect high level goals?

CMcC: Yes, it halps as long as they are not too abstract

ED: Suggested rewording avout remaining in XML

CL: Main aim was that folks using existing xml would not need to change it to copy and paste

DS: Henri said that nonwelformed XML should be exposed as WF by the browser after correction

CMcC: the later ones are higher level goals

DS: So rearrange, and put this one as a consequence. Say why, and then it naturally falls out

CMcC: that more convincing, yes

ED: neither mail captures what we want

CL: Not sure we should push on validity. Well formed is more important

ED: Want the fixups to be arked as errors

CMcC: No implied elements, would restrict ability to change the language
... Parser will need to fix up idf the end tag is wrong

CL: At TPAC, agreement that the doctype etc would not be pasted in

DS: Until there are tools, they will not understand why its not working. Paste in direct from illustrator and inkscape
... Need to ediucate people on what is allowed, some are allowed within XHTL, others within HTML

CL: No doctype etc in the middle, obviously

CMcC: Some examples in my mail

CL: Entities are kind of a transitional phase, just use Unicode nowadays

AG: Omitted quotes is abad idea because with complex syntax its not always clear where the attribute value ends

DS: Lots of attrs take space-less strings and would be fine here, and would be error corrected

<g title=a space string /> with orr characters/>

CMcC: This is error correction?

ED: Not in HTML5, its not an error

DS: Effect is the same.
... depends whether it reports an error or not

AG: I think its inconsistent

DS: Should be flagged as an error to help people who are trying to do standalone svg
... need to be aware of quoting html5 quirks. makes it harder to adapt content

CMcC: Fixed up export helps there

DS: yes
... But mashups, not using a browser, would be effected
... concerned that people have svg-like files, they download the file and try to open in an authoring tool and it does not work. They don't know why

AG: An artist will understand right click, save as, and then open the file

CL: If browsers do silent fixup then there will be svg files that are not well formed and cannot be edited

DS: This is why I said it should be seen as error correction
... no 'visible indication of error' but a log would show a warning
... eg in a validator

CL: Warning is very reasonable.

DS: Would not be surprised to see xml allow this also in the next 5 years
... SVG requires quotes
... Its ok as long as its acknowledged as error correction

ED: Perhaps we should discuss these in email

CMcC: Henri made a fork of Mozilla that uses the old HTML handling of SVG

Vacation break

CL: here next week then off two weeks

<shepazu> http://www.intertwingly.net/blog/

AG: Working to Xmas, then off to 13 jan

DS: Working holiday

CMcC: next week ok?

(agreement seems to be to cancel from22 and restart from 5 Jan

ACTIN: Erik announce the xmas break

<scribe> ACTION: Erik to announce the xmas break [recorded in http://www.w3.org/2008/12/11-svg-minutes.html#action01]

<trackbot> Created ACTION-2377 - Announce the xmas break [on Erik Dahlström - due 2008-12-18].

Selectors review

<ed> http://lists.w3.org/Archives/Public/public-webapps/2008OctDec/0465.html

ED: Some feedback from lachlan

CL: Important thing is that the spec now clearly states that ns functionality is not there. So thats good

ED: Node selector text is also improved
... I mentioned some potential non-interop, and he pushed back. i'm happy to drop those. Selectors on subtrees outside the document will not be interoperable however
... on list creation, its not very precise but its ok i guess
... mention of downlevel clients sparked some discussion
... refuses to add a DOM3 xpath informative reference

DS: Sicking makes good points

ED: On last issue he says he is reconsidering adding an example

<scribe> ACTION: Erik to respond to Lachlan on selectors api review [recorded in http://www.w3.org/2008/12/11-svg-minutes.html#action02]

<trackbot> Created ACTION-2378 - Respond to Lachlan on selectors api review [on Erik Dahlström - due 2008-12-18].

clipping

DS: Not fully convinced by Thomas' argument. Seems to conflate clipping paths with viewports?

CMcC: No, his example is a viewport one but he understands the difference
... he brought in viewports and an example of something that clipped out pointer events

CL: Consider a symbol, which has a clippath. The pointer events are clipped in the other three quadrants unless overflow is enabled

DS: And with visiblePainted, thats what you get

<heycam> http://mcc.id.au/temp/2008/clip-window.svg

DS: Rules fr clip paths apply. Clip paths do not clip events al the time, depends on value of pointer events. Whie whena vireewport is established, events are always clipped itrtespective of the value
... asv clips the events no matter what. safari clips no events at all

CcC: Proposal changes =it to allow either clipping or not

DS: Under author control

CMcC: Thomas' concern is that people have existing content that depends on this. But behaviour is not fully defined in spec.

DS: Is this a real use case?

CMcC: yes, its how people create invisible event targets now
... but there are workarounds

DS: So I don't think this combination is very common as there are better and more direct ways to do this

ED: Interesting to hear Mozilla view on this, would liked to have asked JWatt or RoC

<scribe> ACTION: Doug ask Mozilla about this clipping issue [recorded in http://www.w3.org/2008/12/11-svg-minutes.html#action03]

<trackbot> Created ACTION-2379 - Ask Mozilla about this clipping issue [on Doug Schepers - due 2008-12-18].

ED: Wonder how much content uses clip path plus pointer-events nondefault values

new template for 1.1 tests

<ed> http://lists.w3.org/Archives/Public/public-svg-wg/2008OctDec/0423.html

DS: If we make a schema we could have the validator at W3C be more useful

CL: oXygen ships with a 1.1F XSD, we should get them to add an SVGT1.2 RBG as well

DS: No need for an xml prolog

CL: Apart from non UTF-8, UTF-16, no need for an xml encoding declaration

Resolved: New 1.1F template has no doctype and no xml declaration

(we agree that having one template is a good goal derived versions can be made with xslt)

(discussion on version and baseProfile desirability in tests)

CL: version and baseProfile should only be aded where actually needed. most tests do not require it
... and i agree about the 'approved' value, never understood why that had a different value

ED; There was a distinction between approved an=d accepted, which was that it was published for the public. Used to be a list. Now its autogenerated

CL: Only downside is some (small) changes to the scripts

<scribe> ACTION: Anthony to look through scripts for any breakage that would happen from conflating approved and accepted [recorded in http://www.w3.org/2008/12/11-svg-minutes.html#action04]

<trackbot> Created ACTION-2380 - Look through scripts for any breakage that would happen from conflating approved and accepted [on Anthony Grasso - due 2008-12-18].

ED: Need to clarify what to do when dropping a test back to reviewed or created

Resolved: the approved and accepted should be one value

ED: Wonder if there are tests which are accepted but not approved

meeting adjourned
