This specification defines a new SIP header field, Feature-Caps.  The
Feature-Caps header field conveys feature-capability indicators that
are used to indicate support of features and capabilities for SIP
entities that are not represented by the Uniform Resource Identifier
(URI) of the Contact header field.

SIP entities that are represented by the URI of the SIP Contact
header field can convey media feature tags in the Contact header
field to indicate support of features and capabilities.

This specification also defines feature-capability indicators and
creates a new IANA registry, "Proxy-Feature Feature-Capability
Indicator Trees", for registering feature-capability indicators.
