GEMS13 — Unbounded Lists In Device Definitions

It is not clear how to define the multiplicity of a list of Parameters or ParameterSets when the list is unbounded or can vary in length. For example, if the multiplicity is set to 5, it is assumed this means the list must contain 5 parameters. How does one specify "up to 5" or "unbounded"?

Create standard method of declaring unbounded list sizes. Use a multiplicity of -1 to indicate an unbounded array, while a non-negative and non-zero multiplicity indicates that the array may contain up to the number. For example, a multiplicity of 5 indicates that the array may contain anywhere between 0 and 5 elements.
