<xsd:documentation xml:lang="en">The type of option transaction. From a usage standpoint, put/call is the default option type, while payer/receiver indicator is used for options index credit default swaps, consistently with the industry practice. Straddle is used for the case of straddle strategy, that combine a call and a put with the same strike. This element is needed for transparency reporting because the counterparties are not available, and is made available in other views for convenience; it is not intended to be used for confirmation processing. If the swaption straddle indicator is provided, this must not be in conflict with that indicator.</xsd:documentation>
