Abstract
A number of Internet application protocols have a need to provide
content negotiation for the resources with which they interact [1].
A framework for such negotiation is described in [2], part of which
is a way to describe the range of media features which can be handled
by the sender, recipient or document transmission format of a
message. A format for a vocabulary of individual media features and
procedures for feature registration are presented in [3].
This document introduces and describes a syntax that can be used to
define feature sets which are formed from combinations and relations
involving individual media features. Such feature sets are used to
describe the media feature handling capabilities of message senders,
recipients and file formats.
An algorithm for feature set matching is also described here.
