The RecordSet tag is used to create String[][] matrix where each col is created from values supplied by a ArrayParameter tag. The longest input array will determin the number of rows. Arrays that are shorter will have their values repeated to fill the remaining rows in their col.

In this example there is one orderid value but the item value is already stored as an array of values. The first Ap tag will create an array with one element to store the orderid. The next Ap tag will get item array. The RecordSet tag will combine these into a number of rows where all values in the orderid col are the same but the values in the item col are all different.

<dxp:RecordSet store="oderitems">
   <dxp:Ap name="orderid" require="true"/>    <!-- single orderid -->
   <dxp:Ap name="item" require="true"/>       <!-- multiple items -->
</dxp:RecordSet>
