Diagram comparing schema languages for XML
by Rick Jelliffe
The simple overlapping Venn-like diagrams that people use to express the relative power of schema languages can mislead as well as inform. Instead, here's a kind of diagram with shaded edges: light grey represent capabilities that are possible but inconvenient, and darker grey represent capabilities that are possible but only if you organize your schema in a certain way. XSD extensibility is an example of the darker grey capability: unless you organize your (base) schemas properly, you may easily find extensibility is not possible.
Great Diagram Jeff.
I'd also like to think the Schematron is bigger than XSD!
