Synopsis

</xs:attributeGroup>

Description

Attribute groups are global containers that embed groups of attributes. They can be used to manipulate groups of several attributes often used together, but also to provide global access to attributes that cannot be globally defined because they are unqualified or because several definitions cohabit in a single schema (see the example).

Attribute references or local definitions, attribute wildcards, and attribute group references may be included within attribute group definitions.

Attribute groups may be redefined through xs:redefine elements.

Restrictions

None.

Example

<xs:attributeGroup name="bookAttributes">
  <xs:attribute name="id" type="xs:ID"/>
  <xs:attribute name="available" type="xs:boolean"/>
</xs:attributeGroup>
