DTD for CIAO ComponentAssembly real-time extension.
The extension for this type of XML document should be .RTD
A component server can be associated to one conforming XML
descriptor file of this DTD via the <extension> tag under
<hostcollocation>, <processcollocation> as
<extension class="RT-CAD-EXT"
origin="CIAO">pathname_to_xml_file.xml</extension>
The root element is <rtcad-ext>.
The <extension> tag under <homeplacement> element can be used to
specify the <rtpolicyset> named in this file (using rtpolicyset's
id attribute.) For example,
<extension class="RT-POLICY-SET"
origin="CIAO">IDREF_of_some_rtpolicyset</extension>
