    // If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
    // then the Rfc822Name property returns XML.
    Get ComRfc822Name Of hoCert To sSubjectAltNameXml

    Showln sSubjectAltNameXml

    // Here's a sample of the subjectAltNameXml:

    // <SubjectAltName>
    //     <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>
    //     <name type="oid" oid="2.16.76.1.3.2">JOAO SILVA</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:

    Get Create (RefClass(cComChilkatXml)) To hoXml
