2. Reword the existing paragraph to:
Extension elements can be marked as
mandatory by annotating them with a wsdl:required attribute information
item (see 6.1.2 requiredattribute information item) with a value of
"true". A mandatory extension is an extension that may change the
meaning of the WSDL 2.0 component to which it is attached, such that
the meaning of that component is no longer defined by the WSDL 2.0
language specification. Instead, the meaning of a WSDL 2.0 component
containing a mandatory extension is governed by the meaning of that
extension. Thus, the definition of the component's meaning is delegated
to the specification that defines the extension.
