Description:

This is an empty content, with a single, required attribute, refTo, which is of type uriReference. It is used to reference an instance.

Proposed Usage:

This is a convenience datatype. It is used for tags that reference another instance, but have empty content. Note that earlier versions used type IDREF rather than uriReference.

XML Schema:

The schema and examples do not explicitly show the lines that set the namespaces.

All schema examples will use xsd: as the namespace for the schema tags and datatypes, and null for all the locally generated namespaces.

XML Examples will exclude namespace modifiers for clarity. Actual XML will probably need namespaces.

<xsd:complexType name="reference">
  <xsd:attribute name="refTo" type="xsd:uriReference"/>
</xsd:complexType>

Sample Usage Schema:

   <element name="instanceRef" type="reference"/>

Sample XML:

   <instanceRef refTo="#uid1A"/>
