Example: if the IPerson contained a "role" attribute that were one of three values, "student", "faculty", or "alumni" then to include a layout fragment in the layout for all users having role equal to student the following <dlm:audience> element would suffice.

<dlm:audience evaluatorFactory="campuspipeline.uportal.dlm.IPersonEvaluatorFactory">
<attribute name="role" mode="contains" value="student"/>
</dlm:audience>

Example: if there were a number of roles beyond just these three and a particular layout fragment needed to be included in all roles except for those of faculty and alumni then either of the following <dlm:audience> elements would do the trick although stricly speaking the paren is not needed inside of the <NOT> element.

</dlm:audience>
<dlm:audience evaluatorFactory="campuspipeline.uportal.dlm.IPersonEvaluatorFactory">

<paren mode="OR">
<attribute name="role" mode="contains" value="faculty"/>
<attribute name="role" mode="contains" value="alumni"/>
</paren>
</paren>
</dlm:audience>

Example: The following complex rule shows the capabilities of combining these three elements. The layout containing this <dlm:audience> element would be included for all juniors in any chemistry class or any senior in any biology class except biology 101.
