  	"""
  	Convenience function to construct a document parser with namespaces
  	enabled and validation disabled.  Document validation is a nice
  	feature, but enabling validation can require the LIGO LW DTD to be
  	downloaded from the LDAS document server if the DTD is not included
  	inline in the XML.  This requires a working connection to the
  	internet and the server to be up.
