                   xs:anyAttribute?) )

The xs:attributeGroup element is used to define and reference collections of attributes. Uses of xs:attributeGroup that define the groups must have a name attribute and may include xs:annotation, xs:attribute, xs:attributeGroup, and xs:anyAttribute child elements. Uses of xs:attributeGroup that reference previously defined attribute groups must have a ref attribute and are typically empty, though they may contain an xs:annotation child element.
