Empty Element Types

This section describes the empty element type which can be used to define an XML element with no text content and at least one attribute.

Empty XML Element Type: A special complex XML element that has at least one attribute and no child text content. Empty XML elements must be defined with complex data types in the following format:

<xsd:complexType name="my_data_type">
 <xsd:attribute name="attribute_a" type="data_type_a"/>
 <xsd:attribute name="attribute_b" type="data_type_b"/>
 ...
</xsd:complexType>

Here is an example of an empty element type:

<xsd:complexType name="userType">
 <xsd:simpleContent>
  <xsd:extension base="xsd:string">
   <xsd:attribute name="name" type="xsd:string"/>
   <xsd:attribute name="password" type="xsd:string"/>
  </xsd:extension>
 </xsd:simpleContent>
</xsd:complexType>
