Remarks

The activity defined by the Enhanced Presence Schemas can be expressed by the token attribute value of this element or by one or more custom elements for locale-specific strings.

This element can be extended in future versions of the Enhanced Presence Schemas. The extension is enclosed by ct:delimiter element and a ct:end element in the Enhanced Presence Schemas commontypes namespace, where ct is defined as 'xmlns:ct="http://schemas.microsoft.com/2006/09/sip/commontypes"'.

An extension block can have multiple ct:end elements each of which corresponds to a version of the schema extension.
