[Classpathx-xml] Typo on JAXP Home

[Jeffrey Phillips]

On http://www.gnu.org/software/classpathx/jaxp/ in this paragraph:

If you are using the portable SAX2 bootstrapping APIs, you may want to set
the org.xml.sax.driver system property on each JVM invocation to be
gnu.xml.aelfred2.SAXDriver (non-validating) or gnu.xml.aelfred2.XMLReader
(optionally validating). Otherwise the org.xml.sax.helpers.XMLReaderFactory
may not return the parser you expect.

The gnu.xml.aelfred2.XMLReader validating driver should be
gnu.xml.aelfred2.XmlReader.
