COMMENT:

----------------------------------------------------------------------



== Section 2 ==

It seems a bit odd that some of these terms are re-defined by this document rather than re-using existing definitions, e.g. from RFC 4949 (plaintext, ciphertext, etc.). Was that deliberate?



Thanks for the RFC 4949 reference.  I propose that we use those definitions, where applicable.



== Section 4.1 ==

"As indicated by the common registry, JWSs and JWEs share a common

   Header Parameter space; when a parameter is used by both

   specifications, its usage must be compatible between the

   specifications."



Since both the JWS and JWE specifications are on their way to becoming RFCs, would it make more sense to say "its usage is compatible between the specifications"? Or is this for the future when new parameters may get defined?


This text is applicable both to the current documents and to future registrations in the IANA JSON Web Signature and Encryption Header Parameters Registry.  The registration instructions include this text, reinforcing this requirement:
   The same Header Parameter name can be
   registered multiple times, provided that the parameter usage is
   compatible between the specifications.  Different registrations of
   the same Header Parameter name will typically use different Header
   Parameter Usage Location(s) values.
