Terminate loops unconditionally.
<isbreak> can be used within a loop (defined by an
<isloop> tag) to terminate a loop unconditionally. For more information on creating loops see <isloop>. If
<isbreak> is used in a nested loop, it terminates only the inner loop.
In this example,
<isbreak/> terminates the loop after showing three product names; even if the products iterator contains more than three products.
