ed: heycam didn't see a strong argument either way
... what should we do with this? close it or take it up again?
jwatt: acid3 depends on this behavior?
ed: it did at one time
... we did change the behavior in the spec for the better

ed: didn't we resolve this in second edition?
ChrisL: basically, this is rolling in changes we made in SVGT1.2
... it should be easy to do
<scribe> ACTION: ChrisL to make funcURI consistent, and update tests
[recorded in
[23]http://www.w3.org/2009/11/23-svg-minutes.html#action01]
<trackbot> Created ACTION-2697 - Make funcURI consistent, and update
tests [on Chris Lilley - due 2009-11-30].

http://dev.w3.org/SVG/profiles/1.1F2/publish/types.html#InterfaceSVGViewSpec
<ChrisL> issue-2263?
<trackbot> ISSUE-2263 -- The attributes on the SVGViewSpec interface
are underspecified -- RAISED
<trackbot> [25]http://www.w3.org/Graphics/SVG/WG/track/issues/2263
[25] http://www.w3.org/Graphics/SVG/WG/track/issues/2263
shepazu: we will have to reexamine this in the context of the new
SVG DOM API, anyway
Resolution: defer to SVG 2.0
issue-2294?
<trackbot> ISSUE-2294 -- Adding an animated length attribute into a
baseval length list -- RAISED
<trackbot> [26]http://www.w3.org/Graphics/SVG/WG/track/issues/2294
[26] http://www.w3.org/Graphics/SVG/WG/track/issues/2294
jwatt: I was going to write an email about this...
... maybe we need some custom error about removing items from the
original list (readonly)
... maybe we should have a "copy" method?
... let's address this in the new DOM API
Resolution: move to SVG 2.0
issue-2299?
<trackbot> ISSUE-2299 -- Text on a path layout rules unclear wrt
startpoint-on-the-path and text-anchor -- RAISED
<trackbot> [27]http://www.w3.org/Graphics/SVG/WG/track/issues/2299
[27] http://www.w3.org/Graphics/SVG/WG/track/issues/2299
ChrisL: I don't think they are contradictory, they seem to be saying
the same thing in different ways
... it's using "start point" for 2 different things...
... it's talking about shifting the initial start point
ed: it's ambiguous enough that implementations all do different
things
... but I'm not sure it's critical for SVG 1.1 2nd ed.
shepazu: I want this fixed because it's important... could we start
a 3rd edition errata in addition to SVG 2.0?
ChrisL: we could do... we need to test all of this better, too
ed: one way to start off easy is to have a straight line as the
textPath for tests that describe the start point
ChrisL: good idea
resolution: keep as SVG 1.1 3rd edition errata, but duplicate for
SVG 2.0, to make sure it's addressed in both
issue-2301?
<trackbot> ISSUE-2301 -- Text on a path layout rules unclear wrt
startpoint-on-the-path and text-anchor (svg2) -- RAISED

scroll rather than hidden -- due 2008-09-30 -- OPEN

list activity
ed: discussion about transforms, getIntersectionList, DOM
constructors, image clarification, z-index
ChrisL: I wonder if alex addressed this to their satisfaction?
... a good example might help
<ChrisL> suppose a filter brings in a greyscale image with feimage,
then we do an rgb fecomponenttransfer. that should work
<ChrisL> it wont give an error
<ChrisL> so that is what "as it its promoted to RGBA" means
ChrisL: when we say, "implement as if...", then things that fall out
of the model still have to work
... action to respond to image clarification email with concrete
example
<scribe> ACTION: ChrisL to respond to image clarification email with
concrete example [recorded in
[32]http://www.w3.org/2009/11/23-svg-minutes.html#action02]
<trackbot> Created ACTION-2698 - Respond to image clarification
email with concrete example [on Chris Lilley - due 2009-11-30].
ed: anthony addressed the transforms issues
... Dr. Olaf pointed to his older email... did we address this?
anthony: not sure
ChrisL: Dr. Olaf raised a good point, CSS didn't consider animation
when they specified angles, which need to be normalized, and since
they now have animation this affects them too... we should raise
this with the CSS WG
anthony: I'll take a crack at replying to Dr. Olaf
DOM constructors
<anthony> scribe: anthony
DS: Just started off with basically describing
... what we had proposed
... because he didn't read the proposal page
... just ready the 'what sort of problems we have' page
... he also proposed that we use the innerHTML method for larger
document fragments
... and Brois said that innerHTML has been optimised because
browsers have to parse already
... so that's one thing they optermise for
... Boris seemed to be have mixed responses about sending in a
property bag object for element constructors would help the
performance
... I definitely under the impression from taking to implementers
that setting attributes individually was a huge performance hit
<shepazu> ChrisL: if it's done right, it should be a performance
gain, and is never a performance hit
CL: It can be an atomic operation
<shepazu> shepazu: and it's much nicer for authoring
DS: It's much nicer for authors
<shepazu> shepazu: Jeff may not have considered the issue of the
namespace of an element when he criticized using createElement as an
element method
<shepazu> shepazu: jwatt, what's your impression?
<shepazu> jwatt: boris seemed to refute some of the performance
points that Jeff pointed to
<shepazu> ... but it's about ease of authoring, not so much
performance
<shepazu> ... boris says it's hard to predict performance

http://dev.w3.org/html5/spec/Overview.html#html-fragment-parsing-algorithm
<shepazu> ed: have we verified that innerHTML would work with SVG?
<shepazu> ... I'm reading it, and it doesn't seem great for SVG
<shepazu> jwatt: I can test it, don't know offhand
<shepazu> ACTION: jwatt to test innerHTML for applicability to SVG
[recorded in
[34]http://www.w3.org/2009/11/23-svg-minutes.html#action03]
<trackbot> Created ACTION-2699 - to test innerHTML for applicability
to SVG [on Jonathan Watt - due 2009-11-30].
<shepazu> shepazu: speaking of this, what's the standard way of
doing ASV's printNode?
<shepazu> jwatt: I have a wrapper
<jwatt> [35]http://www.mozilla.org/projects/svg/wrappers.js
[35] http://www.mozilla.org/projects/svg/wrappers.js
<shepazu> ed: maybe for innerHTML, it needs to be put into the
foreign-content mode...
<shepazu> ... otherwise you have to wrap everything in <svg>
<ChrisL> Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.9.3a1pre) Gecko/20091122 Minefield/3.7a1pre
<ed> <html><svg id="foo">...</svg><script>$("foo").innerHTML="<rect
width='100' height='100' fill='green'/></html>
<shepazu> ed: anything that conflicts with HTML element names might
cause a problem
<ed> so test <font>, <video>, <audio>, <textArea>... any others?
<shepazu> jwatt: about the F2F... I'm probably not coming
<shepazu> ... mozilla thinks 4 meetings a year is too frequent
<shepazu> shepazu: actually, I think it's 3 meetings a year now
<shepazu> shepazu: maybe we should examine who would be able to
attend
<shepazu> ed: what about relocating it?
