This document describes a standard method for digitally signing Presence Information Data Format Location Object (PIDF-LO) documents using a subset of the XML Digital Signature specification. A digital signature enables the user of a signed PIDF-LO document to attribute that information to an authorized source within the domain of the target entity. A schema is defined for including a domain authorization element in the PIDF-LO and a set of XML Path Language (XPath) filters for selecting the correct elements for signing.
