// Here's a sample of the subjectAltNameXml:

// <?xml version="1.0" encoding="utf-8"?>
// <SubjectAltName>
//     <name type="oid" oid="2.16.76.1.3.4">...</name>
//     <name type="oid" oid="2.16.76.1.3.2">...</name>
//     <name type="oid" oid="2.16.76.1.3.3">...</name>
//     <name type="oid" oid="2.16.76.1.3.7">...</name>
//     <rfc822Name>...</rfc822Name>
// </SubjectAltName>

// The XML can be parsed like this:

loo_Xml = create oleobject
// Use "Chilkat_9_5_0.Xml" for versions of Chilkat < 10.0.0
