</xs:complexType>

<!– “compose” –>

<!– Domain, codomain and image –>

<xs:element name=“domain” type=“Functions.type”/> <xs:element name=“codomain” type=“Functions.type”/> <xs:element name=“image” type=“Functions.type”/>

<!– “domainofapplication” –>

<xs:group name=“domainofapplication.content”>
