<cabanier> meeting in an hour?
cabanier: I think so, no?
so 20min
cabanier: we set the meeting to UTC instead of Boston time. So
it is independent of time shifts
<heycam> I wonder if I got it right in my message here

<heycam> I said Pacific time would move from 1:30 to 12:30, but
it's just coming up to 1:30 now...
<heycam> maybe I got those two around the wrong way
<cabanier> heycam: yes. it was 12:30. now it's 1:30
<heycam> ok
<heycam> no matter how many times I try to get timezones
right... :)

Shipping paint-order
heycam: Tav did you loo at it
Tav: yes, in FF and Chrome
... works fine
heycam: shall we resolve?
krit: I created a patch for WebKit
... landing today or tomorrow
... unprefix and no compiler flag
... will be in webkit
... what di yoiu want to resolve?
heycam: if it is ok to ship
krit: I would say yes
heycam: agree
... resoltuion
nikos: sounds ok from what I hear
RESOLUTION: The WG is happy with implementations shipping
paint-order in release builds
heycam: we sip erik's topics for now
meetin at TPAC
heycam: the chairs were asked if we meet
... I think we decided already that we want
... but want to verify
krit: last week in october
Tav: in SF
heycam: ppl are complaining having it over halloween
krit: would like not to overlap with CSS WG
... think the CSS WG is meeting monday tuesaday already IIRC
nikos: I think Doug expressed that he would like to meet early
heycam: prefer monday tuesday but not overlap with CSS WG
krit: think there will be possibilities to meet with other WGs
from 111AM to 3PM
... I would be interested in meeting with the a11ky group
richardschwerdtfeger: we are doing implementation guides for
browsers too
... so good idea
... in CA?
krit: yes Santa Clara
richardschwerdtfeger: we did not talk about it yet
... a11ky will probably meet
... will meet with doug about ARIA
krit: I would be interested
richardschwerdtfeger: there is a lot that needs to come
together to get a11ky working
... we are coordinating with HTML5 and other and maybe put it
on github
... I will be editor on SVG2 A11ky guide
... will meet next week first time. Shall we do a task force?
heycam: think it makes sense
richardschwerdtfeger: shall the work be done on github
heycam: what ever editors want to do
richardschwerdtfeger: we are getting toward on DOM and one
a11ky/
... did someone work on tab index yet?
krit: think ed did
ed: working on it
... still in review
... hope to land it soon in Blink
richardschwerdtfeger: I got a bug open on mozilla
whit space attribute
<heycam>
[12]https://www.w3.org/Graphics/SVG/WG/wiki/Proposals/Attribute
Whitespace
[12] https://www.w3.org/Graphics/SVG/WG/wiki/Proposals/AttributeWhitespace
ed: I want to modify attr parsing rules
... compared the types with HTML5
... to see if we have parsing differences
... covered research in the link
... some have additional restrictions on range for numbers or
how many numbers you can specfiy
... mostly floats
krit: I think in filters we have some integers
ed: I'll get to it
... HTML5 has validation requirments
... no wsp before or after numbers
... but relaxed on other types
... in my testing sometimes leading whitespaces are allowed
... for HTML5
ecdwanted to see if we are consistent on parsing rules
ed: but couldn't quite tell
... not sure if it is consistent with how integers are allowed
.. more relaxed
... HTML doesn't have many floating points anyway
heycam: does what you said apply to most attributes or mainly
numbers?
... and should we do that as well? it is not in your proposal
ed: it is nicer if you can require properly written attribute
values
... maybe give validation errors but still accept it
... would like to have it constant between SVG and HTML
krit: didn't you say that HTML is not consistent?
ed: implementations are not consistent
... HTML is very clear although you have to read it forward and
backward a couple of times
... so it is hard to get a clear picture what is excepted when
heycam: do you want to di it by type?
ed: seems fine
... yellow cells means "mostly" allow wsp
... integers are interpreted more or less the same in SVG and
HTML
... but for length and percentage might not be consistent
krit: where do we support length and percentage in HTML?
ed: don't think there is something like that in HTML
krit: what about width <img>?
<ed>
[13]http://www.w3.org/TR/html5/infrastructure.html#valid-non-ne
gative-integer
[13] http://www.w3.org/TR/html5/infrastructure.html#valid-non-negative-integer
ed: they just support integer
... but the spec is non-normative there
<ed>
[14]http://www.w3.org/TR/html5/embedded-content-0.html#attr-dim
-width
[14] http://www.w3.org/TR/html5/embedded-content-0.html#attr-dim-width
ed: it says it has to be in CSS pixels
krit: if there is a unit?
ed: might be ignored
... don't think HTML5 has length attar values
... SVG has some
... most don't say that they take percentage
<ed>
[15]https://www.w3.org/Graphics/SVG/WG/wiki/Proposals/Attribute
Whitespace#Length_values.2C_type:_.3Clength.3E
[15] https://www.w3.org/Graphics/SVG/WG/wiki/Proposals/AttributeWhitespace#Length_values.2C_type:_.3Clength.3E
heycam: I started this at some point
krit: same for me
... in the past we just said length and it meant percentage as
well
heycam: for coords it is the same
ed: filters link to SVG1.1 for coord
krit: I can remove <coord> from Filter effects if needed
ed: don't think it is significant
... looked a t mesh gradients
... x, y are undefined how they parse
... there was a case with width on canvas and video that means
auto
... we don't say what it maps tp
to
heycam: we copied it from img
... would we support wsp for keyword + number?
ed: don't think we allow yet
heycam: ... would we allow wsp for length but not for the
keyword
... do you have a proposal?
ed: not through all examples
... but would like to be consistent
... boolean -> particular rules bit no wsp and no true and
false
... don't think we have any rule for that
... id values mostly from ARIA
... and id attr itself
... text values allow mostly wsp
... some ignore wsp some take it as value
... but did not check all which take wsp and which don't
... event handlers content attributes are parsed to JS rules
... and allow wsp
... not to SVG to decide
... lang values are inconsistent
... have different definitions for that
... cause of land xml:lang source lang
... some allow lists some one vlaues
... browsing context values
... special parsing rules form html
... media queries allow wsp at least on <source?
heycam: should allow wsp
ed: would be nice to get tyne same defintion
... url's can have wsp
... SVG doesn't allow wsp's
... and IRI URI differences
+URL
ed: are wsp's allowed for transforms?
krit: yes they are
heycam: sounds like we should not alliw wsp's for enumerations
ed: for viewer UAs yes, not sure for validators
heycam: think we should be consistent
krit: we may need to consider if wsp can have a meaning
sometimes. but most of the time it shouldn't. So I am fine with
allowing wsp's
ed: will write some tests to check interoperability between UAs
and come back
... do we want to produce the tables automatically somehow?
heycam: we can try that
krit: is it important to know if UAs are interoperable if we
discuss chaging the behavior?
ed: would be nice to know what implementations do
krit: sure but takes time
... did you want to check interop between implementaiotn on SVG
or HTML and SVG?
ed: want to check if one implementation in HTML parses each
type or ignore the values
... want to verify if I understand HTML correctly
... then go on and check SVG
krit: ok
<scribe> ACTION: ed to test behavior on type parsing in HTML
and SVG [recorded in
[16]http://www.w3.org/2014/03/13-svg-minutes.html#action01]
<trackbot> Created ACTION-3600 - Test behavior on type parsing
in html and svg [on Erik Dahlström - due 2014-03-20].
heycam: so we come back to that next week?
ed: yes
heycam: we have 4 min left6
SVG in open type fonts requirements
heycam: the OT spec with SVG glyph needs comments
... there is an open issue about text elements and foreign
object? should it be disabled
... think w agreed on foreignObject
... but didn't discuss text
... but think it makes sense to not allow it
... would just be tricky to specify font usage
... specified on SVG1 but intention is unversioned
krit: what about future elements?
heycam: should we add a definition for a collection of elements
in SVG integration spec
... ppl seem to like this approach
krit: can that be done in a future version of OT SVG?
heycam: it already references SVG integration and I would
suggest to have a WD
krit: don't think that I would want that for current version of
SVG integration
heycam: we can discuss that later
krit: we discussed theree things to the last one: I'd suggest
putting the collection of supported elements into SVG OT
... does MPEG allow referencing EDs?
heycam: not sure, but that is what we do noe
now
<heycam> current draft:

krit: I would prefer having the collection
heycam: would you be ok referencing integration spec?
... thnk comments are to next week and review is in April
krit: don't think svg integration is ready till then
heycam: shall I bring it up on the mailing list?
krit: probably better
