<h2 id="abstract">Abstract</h2>
<p>This document specifies a syntax and processing model for general purpose
content selection or filtering. Selection involves conditional processing of
various parts of an XML information set according to the results of the
evaluation of expressions. Using this mechanism some parts of the information
set can be selected for further processing and others can be suppressed. The
specification of the parts of the infoset affected and the expressions that
govern processing is by means of XML-friendly syntax. This includes elements,
attributes and XPath expressions. This document specifies how these
components work together to provide general purpose selection.</p>
<p>There is a companion document which provides introductory information
concerned with this specification <a href="http://www.w3.org/TR/cselection-primer/">DI
Primer</a>.</p>
