+It is important to note that modules in the \module{xml} package
+require that there be at least one SAX-compliant XML parser available.
+Starting with Python 2.3, the Expat parser is included with Python, so
+the \refmodule{xml.parsers.expat} module will always be available.
+You may still want to be aware of the \ulink{PyXML add-on
+package}{http://pyxml.sourceforge.net/}; that package provides an
+extended set of XML libraries for Python.
+
+The documentation for the \module{xml.dom} and \module{xml.sax}
+packages are the definition of the Python bindings for the DOM and SAX
+interfaces.
