Do you think the reference needs to be included with every use? The US-ASCII subset of UTF-8 is also defined in RFC3629, so I am inclined to use the same reference for that. There are also a couple of uses of US-ASCII without mention of UTF-8. I'm inclined to change those to "the US-ASCII subset of UTF-8". I changed the naked uses of US-ASCII to reference the US-ASCII subset of UTF-8. I also added another reference to RFC3629 to the *first* use of "US-ASCII subset of UTF-8". I haven't added references to other places with the same usage. > Regarding ASN.1 and XDR, I can add references if you think it important. > But their use is very peripheral, and it isn't necessary to know what they are to read the text. > [MW]: I am OK if it is not commonly used. > > # s/session- specific/session-specific/ > > Regarding "session- specific" vs. "session-specific": > > The context for this is: > > "Attribute scopes in addition to media- and session- specific may also..." > > The space was intentional so that there are equivalent constructions for "media" and "session".
