+					<xs:documentation>When the result is an alternative option from IncludeAlternativeOptions, then the flag should be set to true. If it is an alternative option this means that the server decided to add this result for its own reasons: e.g. to push a certain trip leg, because it believes that it might better suit at least some possible customers. Such options are not an optimal fit to the criteria that were in the request. The client may therefore disregard such results depending on the use case.</xs:documentation>
