The <switch> tag

Here is the syntax for the switch tag:

<switch>
 <!-- child1 testAttributes1 -->
 <!-- child2 testAttributes2 -->
 <!-- child3 testAttributes3 -->
</switch>

The rule is:

The first of the <switch> tag children whose test attributes are all evaluated to TRUE is executed.

A tag with no test attributes is evaluated to TRUE.
