Convert an Email to Chilkat XML

Demonstrates the Chilkat Email.GetXml method, which converts the email object to an XML document in memory. The XML is Chilkat's own email-object representation — it is not MIME and not a standardized interchange format. This example builds a message and prints its XML.

Background: This XML form is a Chilkat-specific way to serialize an Email object that can be reloaded with LoadXml / LoadXmlString. Because it is not standard MIME, other mail software cannot read it. In practice the standard .eml format (GetMime / SaveEml) is preferred even within Chilkat-based software: .eml is interoperable and also preserves Chilkat's CKX- metadata headers (which are always removed before an email is sent), so the XML format offers no metadata advantage.
