delete a fragment

Currently you cannot delete a fragment.  However you can change the audience part of a fragment definition to an expression that won't match any users so the fragment will not show up on any user's views.  A recommended fragment definition audience is something like

    <dlm:audience evaluatorFactory="org.jasig.portal.layout.dlm.providers.PersonEvaluatorFactory">
        <attribute name="username" mode="equals" value="nonExistent"/>
    </dlm:audience>
