I have updated the proposal based on the WG call last week. I have also merged in the full description of discriminators. This will be section 7.4 in the dfdl annotations section so will not follow the Uncertainty section. I have also corrected the syntax of the examples. Not all the examples will end up in the spec Regards Alan Powell Development - MQSeries, Message Broker, ESB IBM Software Group, Application and Integration Middleware Software ------------------------------------------------------------------------------------------------------------------------------------------- IBM MP211, Hursley Park Hursley, SO21 2JN United Kingdom Phone: +44-1962-815073 e-mail: alan_powell@uk.ibm.com Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
