Otherwise in Oracle BI Publisher not Working

I have the following XML structure from My Data Set:

<DATA_DS<G_1><INVOICE_NUMBER>20005</INVOICE_NUMBER><BATCH_SOURCE_NAME>MIGRATION</BATCH_SOURCE_NAME><CT_REFERENCE/></G_1><G_1><INVOICE_NUMBER>454162</INVOICE_NUMBER><BATCH_SOURCE_NAME>FM Source Number</BATCH_SOURCE_NAME><CT_REFERENCE>454162</CT_REFERENCE></G_1><G_1><INVOICE_NUMBER>455920</INVOICE_NUMBER><BATCH_SOURCE_NAME>FM Source Number</BATCH_SOURCE_NAME><CT_REFERENCE>455920</CT_REFERENCE></G_1></DATA_DS>

I have put the following logic in my RTF Template inside a FOR-EACH in a Table:

<?choose:?><?when://BATCH_SOURCE_NAME='FreightMaster'?><?CT_REFERENCE?><?end when?><?when://BATCH_SOURCE_NAME='FreightMaster-deactivated'?><?CT_REFERENCE?><?end when?><?when://BATCH_SOURCE_NAME='FM Source Number'?><?CT_REFERENCE?><?end when?><?otherwise:?><?INVOICE_NUMBER?><?end otherwise?><?end choose?>
