(Last updated 10 March 2006)

Attribute Value: first

Description: A URI that refers to the furthest preceding document in a
series of documents.

Expected display characteristics: Undefined; this relation can be used for
background processing or to provide extended functionality without
displaying its value.

Security considerations: Automated agents should take care when this
relation crosses administrative domains (e.g., the URI has a different
authority than the current document). Such agents should also take care to
detect circular references.
