/**	@descr
	Is able to parse an XML file with Component descriptions. Gives access
	to the parsed data.

	Use:
		CompDescrsFromAnXmlFile aCds;
		UniString aFilepath(...);
		if (! aCds.Parse(aFilepath) )
		{
			// react on:
			aCds.Status();
		}

		With operator[] you get access to ComponentDescriptions
		on indices 0 to NrOfDescriptions()-1 .

		For further handling see class ComponentDescription
		in xml_cd.hxx .

		It is possible to parse more than one time. Then the old data
		are discarded.
