Strange bug in XML Serialization/Mapping classes??

[Daniel Cazzulino]

While trying to customize the generated code for an XmlSchema, using the
technique explained in http://weblogs.asp.net/cazzu/posts/33302.aspx, I came
to a point where I can't advance any further as the framework classes are
throwing an exception where they shouldn't.
The customization process basically involves using the XmlSchemaImporter
class and using its ImportTypeMapping() method. To further customize it, I
wanted to modify the type members, therefore, I tried to use the
ImportMembersMapping() with exactly the same (working) XmlQualifiedName used
for the previous method. I got an InvalidCastException thrown in the face
:S. Here's the damn stack trace:

System.InvalidCastException: Specified cast is not valid.

// Works
XmlTypeMapping map = imp.ImportTypeMapping( element.QualifiedName );
// Blows
XmlMembersMapping members = imp.ImportMembersMapping(
element.QualifiedName );-- Daniel CazzulinoLagash Systems
