Selectors API
DS: We should address this as early as possible
ED: Was there anyone else going to review it?
AG: I had an action to review it
... I'll do that today
DS: Having looked at why the CSS WG decided to say never mind on
that issue
... (namespaces) I inclined to let it go
... what do you guys to think?
... do we really want to the SVG WG to be the group that insists on
namespaces
ED: To me realistically want namespaces are you going to encounter?
... I can only see SVG and HTML5 as the opportunity to select only
SVG or HTML elements
... and it's always possible to use DOM3 XPath if you need arbitrary
selection support
DS: If we pushed off namespaces to the second version there is a
very good chance
... that people may not support that version
CM: For the case of between SVG and HTML
... there is probably use the selector itself and look at the parent
to clarify what it is
[discussion on how selection works]
DS: Lets assume that a version gets implemented that doesn't use
namespaces
... I don't think it would be that much harder to implement
... as you're accumulating elements you can always just check the
namespace URI attribute/property
... it would be slower, but only if you're using namespaces
... authors can always do the namespace URI check manually, it's
just a pain
ED: That's why I pushed for an example on the spec on this
... so people can see how to solve the problem
DS: I'll have to go back and look through the whole namespaces thing
... David Baron said that someone had a spec with name spaces, and
he argued that
<ed> spec or impl?
DS: it would go to rec quicker
... I don't know why they dropped it

CM: Do you know which implementations support CSS3 namespaces?
... just wondering the complexity is because of implementing
namespace support in CSS in general or the NSResolver stuff in the
Selectors API?
DS: Not sure
ED: I haven't looked into this I know that Opera has implemented
some of this
... not in my hands to implement, but it would be quite simple to do
... the NSResolvers look fairly simple to me
DS: I'll talk to Lachy and Boris and look at the rationale as why
namespaces was removed
<scribe> ACTION: Doug to Investigate why namespaces was removed
[recorded in
[8]http://www.w3.org/2008/12/01-svg-minutes.html#action01]
<trackbot> Created ACTION-2364 - Investigate why namespaces was
removed [on Doug Schepers - due 2008-12-08].

DS: This seems to be the point at where Lachy says to remove it
... so maybe we should our comments in on Thursday instead
ED: That would be good
Errata

[10] http://lists.w3.org/Archives/Public/public-svg-wg/2008OctDec/0411.html
CM: That looks like what we want
... should change "For example" to e.g.
DS: I tried to word it in such a way that implementors could derive
the value for boundingbox
ED: I like the first paragraph there with the clippath and the
boundingbox
DS: It solves two issues what the boundingbox should be and where
pointer events should occur
... How are we going to make the new spec?
AG: How do you mean?
DS: Are we going to make a new build process like Tiny 1.2 or are we
going to do it manually?
CM: Probably manually
DS: Anthony can you make the changes please. Typos are "and" to "an"
and "e.g" to "i.e"

<trackbot> Created ACTION-2365 - Adds Doug proposed wording to the
errata and make changes as discussed [on Anthony Grasso - due
2008-12-08].
<scribe> ACTION: Doug to Follow up errata proposal on the Email list

[16] http://lists.w3.org/Archives/Public/public-svg-wg/2008OctDec/0408.html
ED: We did get an email from Niklas clamping of rx and ry values
... just wondering if we should errata this
... so I did start writing a new test for this particular issue
... from the testing so far we have more than two ways of doing it
... testing browsers
AG: Did we specify anything in Tiny?
ED: I think it was lifted from 1.1

[17] http://lists.w3.org/Archives/Public/public-svg-wg/2008OctDec/0409.html
NH: In emailed a second test
ED: It does seem to make sense
... So maybe we should discuss briefly which way is more appropriate
... it is difficult to read from the spec which right way
NH: I think we have two options either we to assign ry if it's not
specified and clamp that
... or you should clamp all the way as my last email says
ED: Do you have a preference
NH: Actually it doesn't really matter for me
... easiest way would be to not clamp "ry"
AG: I think in this case what is most intuitive when it comes to
authoring
ED: For for authoring I'd expect to be whatever is clamped for rx
and ry
... then I'd expect that value to be used for the other attribute
(not specified)
NH: It's not that obvious
<scribe> ACTION: Erik to Propose an errata item for rx and ry
[recorded in
[18]http://www.w3.org/2008/12/01-svg-minutes.html#action04]
<trackbot> Created ACTION-2367 - Propose an errata item for rx and

http://dev.w3.org/SVG/profiles/1.1F2/errata/errata.xml#currenttranslate-currentscale-nested-svg
ED: it has a resolution
... looks like Doug raised this
DS: Not sure what the spec says right now
ED: Probably only need to do changes in the structure chapter
<scribe> ACTION: Doug to Propose wording for the change that
addresses the errata item Current Translate Current Scale on nested
SVG [recorded in

ED: There are no links there
... would be useful
... This is probably the start of it
... Might be a good idea to go through
... and find out if Tiny fixed this
DS: We should give this serious thought about how this interacts
with CSS
... we should start coordinating on little issues like this
... will help create a better working relationship with CSS
... The SVG spec should say what the width and height are and should
also allow authors to use that more usefully
ED: There were some changes in Firefox and Opera where the width and
height on the SVG were ignored if the SVG was being used in an
object tag
... we should definitely try to specify it better
<ed> if there was width and height AND a viewbox...and the object
had width and height...IIRC
