An XML qualified name is a namespace qualified local name in the format of namespace:localname.

Because prefixes are only required when XML is persisted or read, they are irrelevant for XmlQualifiedName objects. This class assumes that prefixes are irrelevant. It is the responsibility of the user to ensure the local name does not contain a ":".

For an example using the XmlQualifiedName class, see XmlSchemaAll.

In particular what I was unable to find until I read through the above linked page is more information about the "Namespace" property.

It sounds like it is suppose to be the namespace URI, but the ToString() and static ToString(name, ns) methods make it seem like it is supposed to be a namespace prefix (alias). The linked page makes it clear that is is supposed to be the namespace URI, and that the string output is for convenience and debugging not actual use in an xml document.

I'm really not sure why the static ToString method exists at all if all it does is return 2 strings concatenated with a ':' in between.

Now a ToString method which takes an XmlNamespaceManager and looks up the prefix for the Namespace would actually be useful.
