Set a MIME Body from XML

Demonstrates the Chilkat Mime.SetBodyFromXml method, which sets the body as XML, changes the media type to text/xml, and selects an appropriate transfer encoding. The only argument is the XML text.

Background: This produces an XML-typed part, common in machine-to-machine messaging — SOAP, AS2/EDI payloads, structured data attachments. Marking the content text/xml lets the receiver route and parse it correctly, and Chilkat picks a transfer encoding that preserves the XML across the transport.
