Per discussion at Audio WG f2f 2013-03-26
The conformance section should note that the use of keywords MUST, MAY, SHOULD are used per RFC-2119 and constitute normative statements.
The group did not express a strong preference for either of the following two options. The choice will be left to the discretion of the editor:
1. make sure all normative statements use upper-case MUST, MAY, etc
2. state in conformance statement that all usage of words must, may, should are per RFC2119 and remove/paraphrase all other uses of the keywords, so that only conformance assertions use them.
