Generic Virtualization XQuery

SQL returns tuples (from a newly generated table)

AsTMa? can do that, but it also can return XML content

and AsTMa? statements are rather similar to XQuery statements:

<students>{
   forall [ $s is-a student ]
   return
      <student SID="{$s/in(SID)}">
          <name>{$s/bn}</name>
      </student>
}</students>
