Re: [csswg-drafts] [css-values-4] Switch advanced attr() to being var()-like (#4482)

The latest draft has the attribute name defined as `<wq-name>`, which would make all of these valid:
```css
attr(foo)
attr(m|foo)
attr(|foo)
attr(*|foo)
```
I don't think that last one was intentional, but if it was we need to define what it means with `<element a:foo="1" b:foo="2">`, as attribute order is not significant in XML.
