GEMS14 — Mixed parameter set example has extra delimiter

The mixed parameter set example in 8.2.1.2 has an extra delimiter at the end of the message body:

mixed_param_set:set_type=param_1:int=1,param_2:boolean=true,param_3:string=a short string,

Delimiters should only be between the members of the set. This keeps them consistent with arrays (which, by the way, must NOT have delimiters at the end, since they have to be able to represent string arrays that end with an empty string element).

The ASCII parameter set definition is incorrect

The descriptive text in section 8.2.1.2 first shows an array (instead of a parameter set) and then incorrectly uses a comma as the delimiter.
