For example, an '''address''' or '''company name''' could contain ampersands, so should be included as:
<pre><primarycontact><br /><firstname>Jane</firstname><br /><lastname>Smith</lastname><br /><address><![CDATA[145 Main Street]]></address><br /><companyname><![CDATA[Acme& Friends]]></companyname><br /primarycontact></primary contact> </pre>
* It is advisable to use CDATA for any field containing text since the contents are often unpredictable.
