yes, i intended to use a comma so that each adaptation set's
parameters can be separated by a space. "id" and "streams" are two
parameters for an adaptation set and i have kept them together
separated by comma. if that does not make sense, then i can use space
to separate them and infer it as: any "streams" followed by an "id"
will belong to that "id".
