The Unified Communications Enhanced Presence Schemas are intended for application developers who are interested in publishing or subscribing to enhanced presence within the Microsoft unified communications application framework while maintaining interoperability with Microsoft Office Communicator 2007 R2. The accompanying XML Schema Definition (XSD) files are provided as an application development tool.
