Personally I don't thikn we should link the category since it's irrelevant for understanding the attribute itself, but only for understanding how attributes relate to each other. The previous paragraph is the standard verbiage for how it should be introduced

We use <list-of-urls> for SVG, linking to https://developer.mozilla.org/en-US/docs/Web/SVG/Guides/Content_type#list-of-ts. Remnant from SVG 1

Need to fill this in

 ## Attributes

-This element only includes global attributes.
+In addition to the aria, core, event, and presentation attributes, the `<switch>` element supports the conditional processing attributes:


I haven't seen this verbiage elsewhere. I believe the standard is to say nothing. If you want to add this, we need another PR to update the standard first, because the SVG docs are quite consistent.
