In the version of the spec that I am reading
<http://url.spec.whatwg.org/>, I see definition of an "invalid flag"
<http://url.spec.whatwg.org/#invalid-flag> and a "valid attribute"
<http://url.spec.whatwg.org/#dom-url-valid>.

It would appear that <##> is a valid WHATWGRL but an invalid URI reference.

Under WHATWGRL processing (and as is found in extant browsers), <##>
is handled as it is literally written and not through coercion to a
"valid" address from a "usable" address.

Given these facts, I don't understand how Anne's spec doesn't extend
the space of valid addresses. If the spec says that input is output
without modification and that input is outside of the STD 66 space,
doesn't that expand the space of valid addresses?

WHATWGRLs with "[" and "]" in path, query, and fragment are allowed as well.
