CCC Types in XML

Instance example

<nc:PersonName>
  <nc:PersonGivenName>Jane/nc:PersonGivenName>
  <nc:PersonMiddleName>Elizabeth</nc:PersonMiddleName>
  <nc:PersonSurName>Smith</nc:PersonSurName>
</nc:PersonName>

Schema example

The following shows an example of a subset of type nc:PersonNameType. It is a complex type with complex content (CCC) that contains elements and an attribute.

<xs:complexType name="PersonNameType">
  <xs:annotation>
    <xs:documentation>
      A data type for a combination of names and/or titles by which a person is known.
    </xs:documentation>
  </xs:annotation>
  <xs:complexContent>
    <xs:extension base="structures:ObjectType">
      <xs:sequence>
        <xs:element ref="nc:PersonGivenName" minOccurs="0" maxOccurs="unbounded"/>
        <xs:element ref="nc:PersonMiddleName" minOccurs="0" maxOccurs="unbounded"/>
        <xs:element ref="nc:PersonSurName" minOccurs="0" maxOccurs="unbounded"/>
      </xs:sequence>
      <xs:attribute ref="nc:personNameCommentText" use="optional"/>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>

Schema template

This template shows the creation of a complex type with complex content. It specifies a parent type, two elements, and an attribute.

<xs:complexType name="NAME">
  <xs:annotation>
    <xs:documentation>A data type for ....</xs:documentation>
  </xs:annotation>
  <xs:complexContent>
    <xs:extension base="PARENT_TYPE">
      <xs:sequence>
        <xs:element ref="PROPERTY_1" minOccurs="0" maxOccurs="unbounded"/>
        <xs:element ref="PROPERTY_2" minOccurs="0" maxOccurs="unbounded"/>
      </xs:sequence>
      <xs:attribute ref="ATTRIBUTE" use="optional"/>
    </xs:extension>
  </xs:complexContent>
</xs:complexType>

The cardinality on elements may be adjusted by changing the minOccurs and maxOccurs values. NIEM reference schemas tend to be very flexible, but cardinality should be adjusted in IEPDs to meet specific exchange requirements.

The cardinality on attributes may be adjusted by changing the use value from optional to required.
