An array of TS_BITMAPCACHE_PERSISTENT_LIST_ENTRY structures which describe 64-bit bitmap keys. The keys MUST be arranged in order from low cache number to high cache number. For instance, if a PDU contains one key for cache 0 and two keys for cache 1, then numEntriesCache0 will be set to 1, numEntriesCache1 will be set to 2, and numEntriesCache2, numEntriesCache3 and numEntriesCache4 will all be set to zero. The keys will be arranged in the following order: (Cache 0, Key 1), (Cache 1, Key 1), (Cache 1, Key 2).
