 Each line of the Profile SDP Description consists of text of the form <type>=<value>. <type> is always exactly one character and is case-significant. <value> is a structured text string whose format depends on <type>. It also will be case-significant unless a specific field defines otherwise.  Whitespace is not permitted either side of the `=' sign. In general <value> is either a number of fields delimited by a single space character or a free format string.
