SVG2 User Agent Implementation Guide

<ed> scribeNick: richardschwerdtfeger

Core Accessibility API Mappings

SVG2 Accessibility API Mappings

HTML5 Accessibility API Mappings

<ed> richardschwerdtfeger: does anyone have concerns with the names of the specifications?

<ed> (none heard)

<scribe> scribe: Rich

<ed> http://lists.w3.org/Archives/Public/www-svg/2013Jun/0071.html

should we remove tref from SVG2?

erik: It is not implemented in Firefox. There is not much use in blink. People are looking to remove it if possible.

Rich: Is it implemented in IE?

nikos: Not implemented in IE11

erik: You can use the <use> element instead so not much loss of functionality

nikos: if <use> satisifes those then we will be ok

ed: tref can be used inside a text element. but use you would use outside but you can mostly do the same thing

<nikos> http://lists.w3.org/Archives/Public/www-svg/2013Jun/0075.html

nikos: There was some comment about it breaking air traffic control software
... it was a little bit vague
... If it is not really implemented in browsers anyway …

ed: there were a lot of quirks with it so I would like to remove it. It makes things more complicated for implementation
... If you have script you can do anything with it but there is not always the opportunity to use script
... I propose that we try to drop it with the next publication of the spec.
... hearing no objections

RESOLUTION: Remove TREF from the SVG 2 spec.

Deprecate pixelUnitToMillimeterX, pixelUnitToMillimeterY,

screenPixelToMillimeterX, screenPixelToMillimeterY in SVG2

krit: Do we want to continue having these functions that simply return constants? They are really not needed any more.
... can we at least deprecate them?

ed: So, these contants are easy to get from other APIs or this is basically what the web does more or less
... Can we get these values from CSS?

krit: No, I don’t think so

ed: I have not seen these used so I am not that concerned. I think we should deprecate them.
... hearing no objections to deprecate them.

<scribe> ACTION: Dirk deprecate Deprecate pixelUnitToMillimeterX, pixelUnitToMillimeterY, screenPixelToMillimeterX, screenPixelToMillimeterY in the spec. [recorded in http://www.w3.org/2014/05/08-svg-minutes.html#action01]

<trackbot> Created ACTION-3623 - Deprecate deprecate pixelunittomillimeterx, pixelunittomillimetery, screenpixeltomillimeterx, screenpixeltomillimetery in the spec. [on Dirk Schulze - due 2014-05-15].

Should we use unrestricted double for SVGLength, SVGNumber, SVGAngle and

all attributes?

krit: You can pass none.
... should we restict the API or should we make it unrestricted?
... they will all have unrstricted doubles
... It just makes sense to make it unrestricted.

ed: ok let’s postpone the discussion until heycam is present

All presentation attributes (even the new presentation attributes like

width and height) should allow global CSS keywords like inherit and

initial.

krit: I think we should not add new cases and we should follow CSS as much as possible.

ed: this does post some consistency issues
... … svglength for example. So, that is the reason for not allowing it for the elements that are presentation attributes

nikos: the object models would produce computed styles. This is something we decided 2 years ago.

<ed> <g transform="inherit"> ... and then gElm.baseVal.transform.getItem(0), what does it return?

ed: the base values would be computed?

nikos: you would get the computed styles
... we should move to the CSS object model where possible

ed: you could use the get attributes if you wanted to get whatever was written
... that makes sense
... that would mean that I would go change the spec.

nikos: you would not disallow the new units from CSS
... you are are nto restricting it to the character message length

<scribe> ACTION: ed modify the sentence in the spec. to allow the globall css keywords like inherit and initial [recorded in http://www.w3.org/2014/05/08-svg-minutes.html#action02]

<trackbot> Created ACTION-3624 - Modify the sentence in the spec. to allow the globall css keywords like inherit and initial [on Erik Dahlström - due 2014-05-15].

Event attributes on graphics and container elements why not SVGElement

in general, just like HTMLElement does?

nikos: It would make sense to make it for SVG elements in general
... script elements, style elements, etc.

ed: the scripting chapter in the spec.?
... it is out of date and should be updated.
... these are more or less the standard events

nikos: we just map all event attributes to svg elements as well.

ed: should be fine.

<scribe> ACTION: ed Event attributes on graphics and container elements added to SVGElement just like HTMLElement does [recorded in http://www.w3.org/2014/05/08-svg-minutes.html#action03]

<trackbot> Created ACTION-3625 - Event attributes on graphics and container elements added to svgelement just like htmlelement does [on Erik Dahlström - due 2014-05-15].

ed: the next call is May 22

nikos: I may not be available as well

krit: my regrets

ed: meeting adjouned

<nikos> wonder if I got that in in time ;)
