[Mono-list] empty field

[Dennis Hayes]

	<* System.Xml/XmlQualifiedName.cs: Implemented, but WTF is the
	<Empty field? LameSpec?

	In the graphics point class, point has an empty property that is
true if the x and y position are both = 0.

	Maybe the empty field is true if the qualified name is ""?
	just guessing.
