Questions on API documentation

[NickB]

I couldn't find any use for the following type definitions, as documented at https://api.developer.betfair.com/se...ypeDefinitions

Have I missed something or are they intended for future use?

- Market (looks like a semi duplicate of MarketBook)
- RunnerDescription
- MarketState
- MarketVersion
- MarketRates
- MarketLicence
- MarketLineRangeInfo

Thanks for any help.
