It needs to be stated somewhere.

Because that is exactly what RFC 2045 says. It even appeared (but not
normatively) in my old draft-13.

But the real problems are <parameter> and <value>. In draft-13, I actually
had (simplifying slightly, because there were also RFC 2231
complications):

parameter = [CFWS] token [CFWS] "=" value
value     = [CFWS] token [CFWS] / quoted-string

(again, not normatively)

But I was forbidden from having that stuff incorporated into USEFOR. As a
result, USEFOR does not adequately explain where [CFWS] can appear in
Injection-Info.

OK, if you don't want it fixed, let it go. But just using <domain> in
place of <id-right> will not fix it either, without further verbiage.
