+ * The <i>Group Mutual Exclusion Object</i> is used to describe mutual exclusion
+ * relationships between groups of streams. This object is organized in terms of
+ * records, each containing one or more streams, where a stream in record N
+ * cannot coexist with a stream in record M for N != M (however, streams in the
+ * same record can coexist). This mutual exclusion object would be used
+ * typically for the purpose of language mutual exclusion, and a record would
+ * consist of all streams for a particular language.
