This seems like a very round-about explanation. Considering that this
section is talking about how the JWT PASSporT header is generated, it is
strange that it should be considered normative for the SIP header formation.

Even if the document specifies two opposite things, we should probably pick
the one that makes sense. Quoting a value that is always a token makes
little sense. Unless this document wants to imply that the ppt value is a
quoted string and should always be case sensitive, I see no reason why
quotes are required. In either case, some errata needs to apply either to
this section or to the grammar to avoid future confusion.
