org.relaxng.datatype.Datatype, org.xml.sax.Attributes, .SAXException, com.sun.msv.grammar.xmlschema.Field
XPath matcher that tests one field of a key. This object is created by a FieldsMatcher when a SelectorMathcer finds a match to its selector. This object is responsible for finding a match to one field of the constraint. A field XPath may consist of "A|B|C". Each sub case A,B, and C is tested by a child FieldPathMatcher object. This class coordinates the work of those children and collects actual text that matches the given XPath.
