Hi Jeff,

Just one little thought about STRING data type:

UINTN			the number of UTF-8 tokens
OCTET sequence	UTF-8 encoded character string sequence

I take it that 'number of UTF-8 tokens' means 'number of octets', right? 
Maybe it would be worthwhile to consider adding a 'number 
of /characters/' count in addition to the byte count. This could 
improve performance, particularly when converting to other encodings on 
the client side. Of course any gain must be offset against the 
increased protocol overhead.

The same applies of course to any library string representations.
