<p xmlns="http://www.w3.org/1999/xhtml" ism:ownerProducer="USA" ism:classification="U">Type used to model dates that are approximate, and may not be processable by search engines. Use of the searchableDate is intended to inform search engines when this record should be returned; without it, query matching is system-dependent. This date can be obfuscated for security or other reasons. Example: The information was received on 2010-06-14 but to reduce the risk of compromising the source it is shown in a document as searchableDate start="2010-05-01T00:00:00Z" end="2010-07-01T00:00:00Z"</p>
