Additionally, if you're willing to change your instance, you can add an
xsi:type attribute ([1], [2]) to the variable-named element.  To use the

Now, you'd define varType as a complexType in the schema, and even the
order and contents could be enforced (w, x, y, z).  The schema would still
not enforce that the wildcard specify the xsi:type, and the clear tradeoff
is that your instances would need to specify it in order to get the added
