RulesetIds: The list of identifiers for rulesets supported by the device. A database may require that the device provide this list before servicing the device requests. If the database does not support any of the rulesets specified in the list, the database may refuse to service the device requests. If present, the list must contain at least one entry.
For information about the valid requests, see section 9.2 of the PAWS specification. Currently, FccTvBandWhiteSpace-2010 is the only supported ruleset.
