1 - True multiple dimension array / strings in arrays support
3 - compatibility mode for generating MIDL-readable data:
4 - strip out pidl-specific properties
5 - convert subcontext() to an array of uint8.
6 - perhaps replace subcontext() with something more generic? The argument
7 to subcontext() isn't really intuitive at the moment
9 - don't be so strict on array boundaries.. arrays can and will be empty when
10 a (regular) remote error occurs
12 - support nested elements
