<trackbot-ng> Date: 06 May 2008

<ChrisL> trackbot-ng, status

<ChrisL> hi

<scribe> Scribe: Andreas Neumann

<scribe> ScribeNick: aneumann

ISSUE-2001 - (font-face-dtd): Prose describing <font> content model does not match DTD [SVG Full 1.1]

ED: we discussed it in a previous telcon but did not have a quorum
... in the SVG 1.1 font chapter it says that the font-face element can't appear everywhere where the font element can appear

<ed> http://lists.w3.org/Archives/Public/public-svg-wg/2008AprJun/0005.html

<ed> http://www.w3.org/TR/SVG11/fonts.html#id5195633

<ChrisL> "When used to describe the characteristics of an SVG font contained within the same document, it is recommended that the 'font-face' element be a child of the 'font' element it is describing so that the 'font' element can be self-contained and fully-described."

<ChrisL> implying it need no always be a child of the font element

CL: proposal is to allow it everywhere where font is allowed?

ED: yes font and font-face should be usable at the same places

<ChrisL> Ok that brings it into line with 1.2T as well. In favour

<ChrisL> add the font-face element to Font.class

CL: any issues with recursitivity?

ED: no, can't be nested

<ChrisL> this change in section 20.9.1 Font Content Set and the DTD itself

RESOLUTION: add the font-face element to Font.class

<ChrisL> the DTD is correct already?

<scribe> ACTION: ED to errata the font section and allow font-face everywhere where font is allowed [recorded in http://www.w3.org/2008/05/06-svg-minutes.html#action01]

<trackbot-ng> Created ACTION-2007 - Errata the font section and allow font-face everywhere where font is allowed [on Erik Dahlström - due 2008-05-13].

Japanese Layout Task Force meeting

ED: anyone interested in attending the meeting?

CL: probably, yes
... will reply to Felix
... the meeting seems to be postponed
... but not the TPAC one

<ChrisL> never mind, its the one in April that was postponed, not the TPAC one

XHTML role review

ED:

a few reviews were sent to the public list, from DOH and me

any further review comments should be sent this week

ED: any additional comments?

<ed> http://lists.w3.org/Archives/Public/public-svg-wg/2008AprJun/0007.html

ED: my short review

<ed> http://lists.w3.org/Archives/Member/w3c-svg-wg/2008AprJun/0058.html

CL: I'd say we look forward to working with you on this issue

<ChrisL> Add 'we look forward toworking with WAI PF to define roles suitable for common types of graphis such as maps, charts, etc'

CL: you are asking for the roles to be informative and not normative

ED: its not a complete list

CL: maybe better state it in your reasoning

<ChrisL> say why in the comment, then

CL: I think DOH is only referering to our text element

<ChrisL> first para, change "the elements

<ChrisL> in SVG" to "the text elements

<ChrisL> in SVG

CL: he is correct about text, but other elements do have semantics

<ChrisL> Agree with his point in general

<shepazu> it would also be good for text that doesn't use paragraphs or headings, like poetry, lyrics, etc.

<ChrisL> Additional comment; Its is a pity that no RelaxNG implementation is provided. Please consider adding one.

CL: they only have DTD and W3C XML Schema

<scribe> ACTION: ED to send in comments about XHTML role attribute [recorded in http://www.w3.org/2008/05/06-svg-minutes.html#action02]

<trackbot-ng> Created ACTION-2008 - Send in comments about XHTML role attribute [on Erik Dahlström - due 2008-05-13].

Testsuite issues / actions

ED: AE added a lot of new test cases

CL: reviewing before the F2F would be good

<aemmons> http://www.w3.org/Graphics/SVG/Group/wiki/TestReview

AE: tests are quite different - testing the API
... code layout will need reworking

CL: pretty print in Oxygen can help

<ChrisL> In oxygen - document xml document, format/indent

CL: already reviewed tests should be marked as done

AG: we should also have a comment column

ED: will review SVGMatrix and SVGLocatable

<ChrisL> i will do the color one

<ChrisL> yes

AE: maybe we should involve other implementors like Ikivo more

CL: Doug as staff contact could deal with it - Ikivo should have a representative again

DS: already asked a couple times. Andy seems to be very busy
... they should also send in the revision of MAE

AE: the goal would be to review them before the F2F

<scribe> ACTION: AG to move Test review allocation table to the new wiki and add comment and reviewed column [recorded in http://www.w3.org/2008/05/06-svg-minutes.html#action03]

<trackbot-ng> Created ACTION-2009 - Move Test review allocation table to the new wiki and add comment and reviewed column [on Anthony Grasso - due 2008-05-13].

substring length errata

<ed> http://www.w3.org/Graphics/SVG/Group/track/issues/335

it affects the ACID3 test

ED: its not clear for ligatures or

<ed> surrogate pairs

ED: other TEXT DOM methods specify explicitly what happens in this case
... my proposal is to add a similar sentence to SVGTextContentElement.getSubStringLength definition

<ed> http://www.w3.org/TR/SVG11/text.html#InterfaceSVGTextContentElement

CL: you should never be able to break in the middle of a surrogate pair
... question is in which direction you move

<ChrisL> a selection that points into half of a surrogate pair should expand to include the whole character

ED: second part of the issue is about exceptions if you have a length value that goes beyond the number of characters (taking into account the start offset)
... I don't see the point of the exception

<ed> from selectSubString:

<ed> DOMException INDEX_SIZE_ERR: Raised if the charnum is negative or if charnum is greater than or equal to the number of characters at this node.

<ed> in unsigned long nchars The number of characters in the substring. If nchars specifies more characters than are available, then the substring will consist of all characters starting with charnum until the end of the list of characters.

the exception is fine if you pass a negative value, but other than that we should probably align the the selectSubString way

<ed> <text>abc</text>

<ed> getSubStringLength(0,5)

<ChrisL> text on a path with abcdefghijk

<ChrisL> and the path can display abc

<ChrisL> you ask for substroing len of abcde

CL: what should happen with the invisible characters that can't be rendered along the path

<ChrisL> de are not displayed

ED: not clear from the description of the method

CL: invisible characters don't contribute to the rendered extent

ED: it would affect all of the text methods

CL: sounds like a useful clarification
... it affects all the text methods that depend on the rendering rather than the original characters

ED: will close the original action and we'll open a new one
... still have to mail Ian Hickson

<scribe> ACTION: ED to clarify/errata for text DOM methods in SVG 1.1, specify that unrendered characters don't contribute to the computation; remove exceptions of getSubStringLength; clarify about unseparable characters [recorded in http://www.w3.org/2008/05/06-svg-minutes.html#action04]

<trackbot-ng> Created ACTION-2010 - Clarify/errata for text DOM methods in SVG 1.1, specify that unrendered characters don't contribute to the computation; remove exceptions of getSubStringLength; clarify about unseparable characters [on Erik Dahlström - due 2008-05-13].
