Save MIME as an XML File

Demonstrates the Chilkat Mime.SaveXml method, which writes Chilkat's MIME XML representation to a local file. The only argument is the file path; the file can later be loaded by LoadXmlFile.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: The file-writing form of GetXml, for persisting a message's structure as XML that LoadXmlFile can reconstruct. This XML round-trip is a convenient way to store or version a message in a format editable with standard XML tooling.
