HTML Validator does not allow role="presentation" or role="none" on SVG elements

[jongund]

I am trying to add role="presentation" or role="none" to the SVG elements in the Slider Thermostat example in pull #1755, and I am getting html linting errors that these roles are not allowed on the SVG element:

Error: "file:/home/runner/work/aria-practices/aria-practices/examples/slider/slider-thermostat.html":58.13-58.84: error: Bad value “presentation” for attribute “role” on element “svg”.
Error: "file:/home/runner/work/aria-practices/aria-practices/examples/slider/slider-thermostat.html":81.13-81.83: error: Bad value “presentation” for attribute “role” on element “svg”.

The same error is generated for role=none on the SVG element.

I think the upstream bug is validator/validator#1096

@nschonni
How do we get this fix for role on SVG in our linter?

Errors/warnings can be suppressed in https://github.com/w3c/aria-practices/blob/main/.vnurc. I'd probably point to the upstream tracking bug as a comment or point to this issue and leave it open till the upstream is fixed

I tried to add something to the .vnurc file in my pull request, but that doesn't change the error:
bcbdeed

Sorry I am not familiar with the VNU validator configuration, who can add the regex statement to allow the role attribute on SVG elements and what file needs to be changed and in which branch?

@nschonni
Thank you for the help, that fixed it.
