props | Root attribute from which new metadata attributes can be specialized. | CDATA | #IMPLIED | No
base | A generic attribute that has no specific purpose.

Alternatively, the props attribute may be specialized to provide a new metadata attribute instead of using the general otherprops attribute. | CDATA | #IMPLIED | No
rev | Indicates a revision level of an element that identifies when the element was added or modified. It may be used to flag outputs when it matches a run-time parameter; it cannot be used for filtering. It is not sufficient to be used for version control. | CDATA | #IMPLIED | No
