Abstract:
This specification creates a new IANA registry, "Proxy-Feature
Feature Caps Trees", for registering "feature caps", which are used
by SIP entities not represented by the URI of the Contact header
field to indicate support of features and capabilities, where media
feature tags cannot be used to indicate the support.
This specification also defines a new SIP header field, Feature-Caps,
to convey feature caps in SIP messages.
