The <SomeElement> element must be of the General type (empty and with
no attributes) unless it has an xsi:type attribute. If it has an
xsi:type attribute then the type named in that attribute must be a
type derived from the General type; it can be derived by restriction
(though it's impossible to restrict the General type any further) or
by extension.
