Load MIME from XML

Demonstrates the Chilkat Mime.LoadXml method, which reconstructs a MIME tree from Chilkat's MIME XML. The only argument is the XML string.

Background: Chilkat can represent a MIME tree as XML — headers as elements, parameters as attributes — which is convenient for inspecting or editing structure with XML tools. This is the inverse of GetXml: it rebuilds the full MIME object from that representation. Invalid XML leaves the current object unchanged.
