Encapsulates parts of a market data rule relating not to the nature of the market data requested, but rather the nature of the thing (instrument/model) that is requesting it.
In the first instance, this includes the instrument type, asset class, and the currency of the underlying instrument.
This can be used to differentiate requests for market data according to the source of the request. See MarketDataSpecificRule.
