     <a href="#mentionOf" class="qname">prov:mentionOf</a> is a special type of <span class="repeated">prov:specializationOf</span> whose subject presents as an aspect a particular <span class="repeated">prov:Bundle</span> in which its more general Entity was described (<a href="#asInBundle" class="qname">prov:asInBundle</a> is used to cite the Bundle in which the generalization was mentioned).

+      <p>The "Mention" construct might be removed from PROV if implementation experience reveals problems with supporting this construct. 
+      Since PROV-O uses <span class="repeated">prov:mentionOf</span> and <span class="repeated">prov:asInBundle</span> to encode "Mention", these two properties might also be removed under the same conditions.</p>

       The <strong>third</strong> category allows further description of Entities. The property <a href="#value" class="qname">prov:value</a> holds a literal value for the Entity. For example, the <span class="repeated">prov:value</span> of a quote could be a string of the sentences stated, or the <span class="repeated">prov:value</span> of an Entity involved in a numeric calculation could be the xsd:integer four.
