The proposal does both. Are you saying I should file separate 
registrations for whether something is a hyperlink or an external resource 
link, and whether something is allowed on <link> or <a>/<area>? I suppose 
we could do that but that would just make the interface with the HTML spec 
a bit more complicated, and I don't understand how that would help anyone. 
Are other languages also interested in the distinction between hyperlinks 
and external resource links? I assumed this was just an HTML issue.

I don't understand how it affects noreferrer. That keyword isn't listed in 
the registry and isn't in the proposal as far as I can tell.

At this point I'm unsure how to proceed. Is the registration request 
denied? Should I just send the request again but listing the keywords that 
are not allowed rather than the keywords that are hyperlinks, and with the 
default switched around? I don't really understand this process.
