This is not exactly consistent with the universal selector, since it uses
the default namespace:
@namespace "foo";
@namespace a "foo";
* {}
a|* {}
Those two are equivalent but different to *|*.

Consistency with XPath seems like a weird motivation if the move to
Selectors in ITS was because people are more familiar with Selectors.
When would you want to select all attributes, by the way?
How do you declare a namespace prefix for the selector in ITS when using
Selectors?
