Issue70 profile names2

I just rewrote this. 
I was thinking something like 
OLD
  <t>Any profile matching the following patterns MUST be accepted:
              "RTP/[S]AVP[F]" and "(UDP/TCP)/TLS/RTP/SAVP[F]"</t>
             <t>Because DTLS-SRTP is required, SAVP and AVP MUST be treated
            identically as indicating DTLS-SRTP.</t>
NEW
  	<t>Any profile matching the following patterns need to be considered:
          "RTP/[S]AVP[F]" and "(UDP/TCP)/TLS/RTP/SAVP[F]". The variants with 
	SAVP or SAVPF MUST be accepted. The variants with AVP or AVPF MUST be 
	accepted and if there is an "a=fingerprint" attribute as that indicates 
	to use DTLS-SRTP but MUST be rejected if there is no "a=fingerprint" 
	attribute since DTLS-SRTP is required. </t>
