//  If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
//  then the Rfc822Name property returns XML.

//  Here's a sample of the subjectAltNameXml:

//  <SubjectAltName>
//      <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>

//      <name type="oid" oid="2.16.76.1.3.3">02408939000115</name>
//      <name type="oid" oid="2.16.76.1.3.7">000000000000</name>
//  </SubjectAltName>

//  The XML can be parsed like this:

oXml:LoadXml(cSubjectAltNameXml)
