An attribute domain vocabulary module declares one new attribute specialized from
either the @props or @base attribute.
All vocabulary and constraint modules must document their
@domains attribute contribution. The OASIS grammar files use a
<dita:domainsModule> element to document the contribution; this
element is used consistently to make it easy to find values when creating a document type
shell. An XML comment or <xs:appinfo> element can also be used.
An attribute domain consists of one file. The file must have a single attribute group
definition that contains the definition of the attribute itself, where the attribute group is
named attnameAtt-d-attribute.
@deliveryTarget attribute is defined
with the following attribute
group:<xs:attributeGroup name="deliveryTargetAtt-d-attribute">
<xs:attribute name="deliveryTarget" type="xs:string">
<!-- Documentation for attribute -->
</xs:attribute>
</xs:attributeGroup>
