Comments are welcome here or in my original blog post regarding this table.
@chris-martin, @havenwood to give you a real-world example for the hex encoding ("45" => "3435"): http://books.xmlschemata.org/relaxng/ch19-77143.html
this is quite inefficient, I know, but you sometimes need it for backwards compatibility.
