13.2. SDP message format
The SDP syntax is very strict and all lines follow the same format. Every SDP line has the format:
<character>=<value>
No spaces are allowed on either side of the "=" sign. The <value> part of the line contains one or more parameters and there is exactly one space between each parameter:
value=parameter1 parameter2 ... parameterN
Each SDP line ends with a Carriage Return–Line Feed (CRLF) and each line has a defined number of parameters.
