The following is an XML example for a SelfSchedule:

<BidSet xmlns="http://www.ercot.com/schema/2007-06/nodal/ews" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.ercot.com/schema/2007-06/nodal/ews ErcotTransactions.xsd">
    <tradingDate>2008-01-01</tradingDate>
    <SelfSchedule>

            </TmPoint>
        </EnergySchedule>
    </SelfSchedule>
</BidSet>
