[stir] Question about "RPH Types" RE: I-D Action: draft-ietf-stir-rph-00.txt

I am having some difficulty understanding "RPH types"

Section 5 says
" A new IANA registry has been defined to hold potential values of the "rph" array; see Section 8.3."
<there is no Section 8.3.  This may be a typo for 6.2>

Within Section 6, IANA considerations, Section 6.2 says:

" This document requests that the IANA create a new registry for PASSporT RPH types.  Registration of new PASSporT RPH types shall be under the specification required policy. This registry is to be initially populated with a single value for "namespace" which is specified in [RFCThis]."

But I can find no reference to "RPH types" in the rest of the document.  Nor can I find any other references to "rph" array.  And I can't  find anything that indicates  what this a single value for    "namespace" is.

So I am not sure how it/they will be used.

Some additional description and clarification would be useful.

Janet

Abstract:
   This document extends the PASSporT object to convey
   cryptographically-signed assertions of authorization for
   communications 'Resource-Priority'.  It extends PASSporT to allow
   cryptographic-signing of the SIP 'Resource-Priority" header field
   which is used for communications resource prioritization.  It also
   describes how the PASSPorT extension is used in SIP signaling to
   convey assertions of authorization of the information in the SIP
   'Resource-Priority' header field.
