public class XMLProperties
extends Properties
A subclass of java.util.Properties which uses XML as it's save format. The result is more flexable, strings can contain arbitary characters that Properties doesn't like ('=', for one, IIRC).

Pass the system property "XMLProperties.parser" with an appropriate value to set the parser to use, otherwise it will attempt to use Jim Clark's XP. Whichever parser is used, it must be in the classpath for the whole thing to work. The SAX 1.0 API classes (org.xml.sax.*) must also be in the current classpath.

fix: put DTD here, for now, run the test, it will generate a sample.
