Should SVG's <script> element support the fetchpriority attribute analogous to HTML's <script> element?

w3c/svgwg#916

karlcow: implemented in Firefox and a not-merged patch in WebKit. Not implemented in Chrome.

karlcow: Is Chrome interested? Not part of the SVG spec right now.

Vinay: Async is in Chrome but not fetchpriority.

Vinay: I have to get back since the involved team has issues with the XML parser. But async ships.

<karlcow> https://wpt.fyi/results/svg/scripted/attr-script-fetchpriority.html?label=experimental&label=master&aligned

ACTION: Vinay to investigate if this is in th einterest of Chrome to have fetchpriority attribute on SVG script element

Editorial] Convert main specification to bikeshed

w3c/svgwg#1036

karlcow: Will make more progress next week.

karlcow: I hope to finalize by EOY

[Editorial] missing word attribute in 6.1 section about styling.

w3c/svgwg#1041

karlcow: Minor: There is a sentence in the spec with a missing work about the style attribute. Should we add it?

krit_: Suggestion is to make the text formative, add a MUST and the word attribute. Only the information about SVG 1.1's behavior stays informative? I agree to your change suggest.

Vinay: me too

RESOLUTION: A the word attribute, make the text formative with a MUST. Follow the change suggestion from Karl on the ticket

[WPT maintenance] fixing xlink:href in tests

w3c/svgwg#1042

karlcow: There are a lot of usages of xlink:href in the spec. Should we replace it everywhere?

krit_: Are you confident that all browsers and editors support the href w/o prefix?

nzimmermann: How would we know which applications support SVG in general. Do we have a list?

krit_: SVG is widely used as interchange format on clipboard for various applications from InkScape to Illjustrator and borwser apps. Each app may have their own implementation with the own parser. I am not confident that they all support hred. Illustrator doesn't for example.

nzimmermann: We can deprecate it, but in the ticket Karl says something about the precedence which one to use href / xlink:href.

nzimmermann: wait, it is in the spec but not being tested

karlcow: it is in the spec and yes, Chrome team added a test

<krit_> s/no test/Chrome team added a test/

karlcow: question here is: Do we remove it?

nzimmermann: there could be a meta test for href and xlink:href

krit_: Do all browsers at least support href? Then we would have 3 implementatinos?

karlcow: yes, green everywhere with a few minor bugs in WebKit

caribou: and do we know about editor applications?

karlcow: the class of applications woul need to implement href AND use WPT

karlcow: We could decide to make href a prefix of xlink:href. But this is not the point for WPT.

nzimmermann: WPT is WEB platform. So we should remove the Xlink prefix where possible.

nzimmermann: good to get this off and align HTML and SVG more.

nzimmermann: IMO this only affects browsers. In reality, most other applications would not even use WPT.

Vinay: We will just have breaking tests that no one will fix.

ydaniv: In favor of removing it but did see XML based parser implementagtions of SVG which had the issue.

RESOLUTION: Remove xlink: prefix on href in all WPT tests w/ exception of the meta test to verify behavior on xlink:href to href

[WPT] Testing deprecated xlink:href and precedence of href #1043

w3c/svgwg#1043

karlcow: Chrome team submitted a test to test precedence of href to xlink:href. So issue is fixed.

nzimmermann: did you review it?

karlcow: I will double check

Next meeting

krit_: Next meeting on Jan 8.
