java.lang.Object net.sf.saxon.event.SequenceReceiver net.sf.saxon.event.ProxyReceiver com.saxonica.validate.IdValidator
public class IdValidator
This class validates that ID elements and attributes have unique values and that IDREF and IDREFS elements and attributes refer to an ID in the same document. The class assumes that these elements and attributes have already been locally validated (so, for example, a element of type ID will not have child elements).
