- lastValidIndex (Int32)
- Last valid index for the collection (i.e., maximum count - 1).

lastValidIndex is used instead of maximum count so that maximum type values may
be specified as needed. For example, if the protocol specifies a collection with a signed 16-bit
maximum length you can specify MaxValue (i.e., 32,767) as the last valid index
for the collection since total number of items supported would be 32,768.
