Description
Used to extend the content model of an
existing complex type. When deriving a new complex type
by extension, the content model of the derived type is
considered to be a sequence consisting of the content
model of the base type followed by the content model of
the extension. An extension type will be valid in any
content model where its base type is valid, however the
xsi:type attribute must be used in the instance to
indicate the extension type being used.
