This document provides an Extensible Markup Language (XML) Schema for
the Call Processing Language (CPL). The original CPL specification
only provides a Document Type Declaration (DTD) to describe the
structure of the language. Compared with XML DTDs, XML schemas have
many advantages such as performing stricter type checking, providing
pre-defined data types and being able to derive new data types from
existing ones. We further split the CPL schema into two parts, one
contains elements common to all the telecommunication entities, such
as user agents or presence agents. The other contains elements, such
as 'proxy', specifically for network servers.

In the body type:
"FILE /internet-drafts/draft-wu-cpl-schema-02.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
