aoqi@0	40	/**
aoqi@0	41	* Implements "response context" on top of {@link Packet}.
aoqi@0	42	*
aoqi@0	43	* <p>
aoqi@0	44	* This class creates a read-only {@link Map} view that
aoqi@0	45	* gets exposed to client applications after an invocation
aoqi@0	46	* is complete.
aoqi@0	47	*
aoqi@0	48	* <p>
aoqi@0	49	* The design goal of this class is to make it efficient
aoqi@0	50	* to create a new {@link ResponseContext}, at the expense
aoqi@0	51	* of making some {@link Map} operations slower. This is
aoqi@0	52	* justified because the response context is mostly just
aoqi@0	53	* used to query a few known values, and operations like
aoqi@0	54	* enumeration isn't likely.
aoqi@0	55	*
aoqi@0	56	* <p>
aoqi@0	57	* Some of the {@link Map} methods requre this class to
aoqi@0	58	* build the complete {@link Set} of properties, but we
aoqi@0	59	* try to avoid that as much as possible.
aoqi@0	60	*
aoqi@0	61	*
aoqi@0	62	* <pre>
aoqi@0	63	* TODO: are we exposing all strongly-typed fields, or
aoqi@0	64	* do they have appliation/handler scope notion?
aoqi@0	65	* </pre>
