<heycam> ScribeNick: heycam
Publication schedule
DS: It's important that we get the 1.2 Tiny spec to Rec by the end
of the year
... because we have several standards bodies that have deps on this
spec that need it to become Rec
... it's important for the mobile use
... i think it's important that SVG start focussing more on desktop
browser uses soon
... in order to do this, we need to go to LC by the end of next
month at the latest
ED: what do we need to get done for LC by the end of next month?
... the changes appendix will need to be updated
CM: a lot of work there
... what level of changes should we include there?

trackbot, close ISSUE-2014
<trackbot> Sorry, heycam, I don't understand 'trackbot, close
ISSUE-2014'. Please refer to
[40]http://www.w3.org/2005/06/tracker/irc for help
[40] http://www.w3.org/2005/06/tracker/irc
[41]http://www.w3.org/Graphics/SVG/WG/track/issues/2021
[41] http://www.w3.org/Graphics/SVG/WG/track/issues/2021
We decide to punt ISSUE-2021 to SVG Core 2.0.
ISSUE-2021: ASV returns (0,0,400,400) for the test case.
<trackbot> ISSUE-2021 Bounding box of <image> subject to
aspect-ratio preservation undefined notes added
[42]http://www.w3.org/Graphics/SVG/WG/track/issues/2022
[42] http://www.w3.org/Graphics/SVG/WG/track/issues/2022
We decide to move ISSUE-2021 to Core.
CM: i don't think it should be unsupported or in error
... it should be valid, and then the processing due to eRR just
happens if the resource is 404 or whatever
ED: eRR would mean that the rendering would stop there
<ed> so if you have an svg with three images in it, the svg has
eRR="true" and then the second image is 404
<ed> then no image would be visible because of eRR
<ed> it's not in error, and the IRI isn't unsupported
<ed> it's just an effect of eRR handling
DS: unsupported values should be shown in the error console
... we can have a suggestion in the spec to say that if the UA has
some notion of an error console or log, that it reports unsupported
values and how they were remedied (the lacuna value used, etc.)
<scribe> ACTION: Doug to add the suggestion to report unsupported
values in the error console [recorded in
[43]http://www.w3.org/2008/08/21-svg-minutes.html#action02]
<trackbot> Created ACTION-2143 - Add the suggestion to report
unsupported values in the error console [on Doug Schepers - due
2008-08-28].
DS: in Linking it says "a circular references represents an error",
i don't like this
we decide to leave that to be an error
<ed>
[44]http://dev.w3.org/SVG/profiles/1.2T/publish/struct.html#External
ResourcesRequiredAttribute
[44]
http://dev.w3.org/SVG/profiles/1.2T/publish/struct.html#ExternalResourcesRequiredAttribute
<ed> Indicates that resources external to the current document are
required. If an external resource is not available (for example the
request for the required resource times out), progressive rendering
is suspended, the load event is not fired for the element, and the
document goes into an error state (see Error processing). The
document remains in an error state until all required resources
become available.
<ed> so...we should sync the wording in linking with this, saying
"error state" but not "in error"
<shepazu> hi, aemmons!!
<ed> From linking: "When attribute externalResourcesRequired has
been set to true on the referencing element or one of its ancestors,
then an unresolved external IRI reference (i.e., a resource that
cannot be located) shall represent an error (see Error processing)."
[We discuss the newly introduced fallback behaviour in the Linking
chapter, and decide it's too much of a change to introduce this
late, and we'll move it to Core.]
We need an action to make the following changes in this section:
- move the first dot point about circular IRI references to a
paragraph of its own (so it doesn't just apply to invalid IRI
references, but any circular references
<ed> Replace:
<ed> When attribute externalResourcesRequired has been set to true
on the referencing element or one of its ancestors, then an
unresolved external IRI reference (i.e., a resource that cannot be
located) shall represent an error (see Error processing).
<ed> With:
<ed> Note that when the attribute externalResourcesRequired has been
set to true on the referencing element or one of its ancestors, then
an unresolved external IRI reference (i.e., a resource that cannot
be located) will result in special handling, see [definition of
eRR].
- Add an "invalid IRI reference" definition to intro.html
- Check that processing for invalid IRI references is defined for
each attribute that can have an IRI reference
- Move the third bullet point to Core.
<scribe> ACTION: Cameron to rework the invalid IRI reference section
(14.1.4) as in the minutes here [recorded in
[45]http://www.w3.org/2008/08/21-svg-minutes.html#action03]
<trackbot> Created ACTION-2144 - Rework the invalid IRI reference

ED: there were some files that referenced from <animation> elements
something that had overflow
... i recall fixing some of those or all of those cases i found so
that they contained the graphics within their area, so clipping
wasn't an issue
AG: and when i investigated julien's email, i found that opera and
bitflash did the same thing and produced the reference image we had
... so i suspect julien looked at the old version of the test suite

ISSUE-2030
[51]http://www.w3.org/Graphics/SVG/WG/track/issues/2030
[51] http://www.w3.org/Graphics/SVG/WG/track/issues/2030
ED: Dino said he had an action to clean up feature string
... Chris says that Mobile 1.1 had incorrect feature strings
... compared to 1.1 Full
... but does Tiny 1.2 have new feature strings?
CM: Dunno
... so in Tiny 1.2 does it have any of the 1.1?
ED: Tiny doesn't have any of 1.1 feature strings
... not sure if this was deliberate (Tiny 1.2 new ones)
CM: In the minutes from 2005 there was suggestion from Scott to
change them and issue an errata for 1.1
... so this issue is now on Mobile 1.1
... and the decision was they we not going to change the 1.2 feature
strings
<ed> [52]http://www.w3.org/TR/SVGMobile/Tiny/feature
[52] http://www.w3.org/TR/SVGMobile/Tiny/feature
ED: SVG Tiny 1.1 feature strings there are 3 of them, I think
<ed> [53]http://www.w3.org/TR/SVGMobile/Basic/feature
[53] http://www.w3.org/TR/SVGMobile/Basic/feature
ED: Not sure if there is anything we need to fix for 1.1 Tiny or
Full
CM: It does list 1.0 feature strings
... so it's a bit of a mess
... I guess we are not going to change anything for Tiny 1.2 either
then
ED: What exactly is the issue about?
... seems to have been changed
... but not sure
... I think it could be a problem that there is no hasFeatureMethod
Tiny
... I wouldn't mind seeing a new Issue raised to address the problem
of missing hasFeature method
CM: What it says in the original mail doesn't seem to be problem
anymore
<heycam> ScribeNick: anthony
RESOLUTION: We will close the ISSUE-2030 as it does not effect Tiny
1.2
ED: I'll raise a new issue about hasFeature to replace ISSUE-2030
ISSUE-2031
[54]http://www.w3.org/Graphics/SVG/WG/track/issues/2031
[54] http://www.w3.org/Graphics/SVG/WG/track/issues/2031
CM: [Reviews minutes]
ED: Is this something that would work in Batik?
CM: Not implemented
<heycam> "When an element is not displayed (i.e., when the 'display'
property on that element or one of its ancestors has a value of
none), that element must not be the target of pointer events."
<heycam> -- 13.7
ED: I think this wording is a bit unclear
<ed> so, if the element has display=none then I don't expect any
user interaction to create events that has that element as its
original target
<ed> ...but on the other hand I do expect the element (if it's in
the document) to still be able to receive events that are dispatched
to it
<ed> ...with dispatchEvent, or by other means
<aemmons> I agree with ed 100%
<ed> so if an element that has focus is made invisible with a
display=none, what is expected to happen with the current focus?
<ed> is it still focused?
<aemmons> nope, focus is re-evaluated
<aemmons> lots of content does this
<aemmons> a few groups of 'menus'
<ed> that's undefined behaviour as I read the spec
<aemmons> enable display only on one
<aemmons> move display through various groups for a different menu
<ed> do you have any pointers for where it says the focus must be
moved on display=none?
<aemmons> sure, sec..
<aemmons> [55]http://www.w3.org/TR/SVGMobile12/interact.html#focus
[55] http://www.w3.org/TR/SVGMobile12/interact.html#focus
<aemmons> The SVG User Agent must not navigate to an element which
has display='none'. (An element which has display='none' is not
focusable.)
<aemmons> The SVG User Agent must allow navigation to elements which
are not visible (i.e. which has a 100% transparency or which is
hidden by another element).
<ed> but it wasn't display=none when it became focused
<aemmons> Yes, Dos not explicitly say if it is changed that a new
focus is chosen
<aemmons> But, early on in 1.2 content and implementation, it was
implied
<aemmons> by us, but also content tools and developers
<aemmons> and also I beleive other impleemntations
<aemmons> I guess if it is not obvious something has to be added to
clarify either way
<aemmons> But I believe the usefulness of content would be reduced -
how in content then would you force a change in focus without
resorting to ECMAScript?
<ed> I'll send an html example to the publicwg list
<aemmons> ok, my example still stands in the original issue - this
type of construct is very useful for making UIs with SVG
<ed> the thing is though, focus handling is really tricky stuff, and
I don't want HTML and SVG to be incompatible because that makes it
even more complex
<ed> see

1.html
[56]
http://lists.w3.org/Archives/Public/public-svg-wg/2008JulSep/0171.html
<ed> firefox and opera keeps the first field focused, even after it
was display=none:d, and after redisplaying it you can continue to
type into it
<ed> safari doesn't move the focus anywhere, but doesn't allow
typing more characters
<ed> (well, the field still has a focusrect in safari)
<ed> btw, apologies for the broken html...
DS: If that's not the specified behavior then we should examine the
behavior
... we should probably coordinate with HTML on this
<scribe> ACTION: Doug to take up ISSUE-2031 with the HTML WG
[recorded in
[57]http://www.w3.org/2008/08/21-svg-minutes.html#action07]
<trackbot> Created ACTION-2148 - Take up ISSUE-2031 with the HTML WG
[on Doug Schepers - due 2008-08-28].
<aemmons> Ok Erik, I see where you are coming from. This is an
interesting problem but please we should not do anyhitng hastly -
the whole mobile content that I can see from both us and other
relies on focus a given way
<aemmons> to the point where if it were deiced the other way we'd
have to be non-compliant or else tick off a lot of people
<aemmons> I am sure this is not just us as well but others
