aoqi@0	37	* Implemented by the driver of the compiler engine to handle
aoqi@0	38	* errors found during the compiliation.
aoqi@0	39	*
aoqi@0	40	* <p>
aoqi@0	41	* This class implements {@link org.xml.sax.ErrorHandler} so it can be
aoqi@0	42	* passed to anywhere where {@link org.xml.sax.ErrorHandler} is expected.
aoqi@0	43	*
aoqi@0	44	* <p>
aoqi@0	45	* However, to make the error handling easy (and make it work
aoqi@0	46	* with visitor patterns nicely),
aoqi@0	47	* none of the methods on this class throws {@link org.xml.sax.SAXException}.
aoqi@0	48	* Instead, when the compilation needs to be aborted,
aoqi@0	49	* it throws {@link AbortException}, which is unchecked.
aoqi@0	50	*
aoqi@0	51	* <p>
aoqi@0	52	* This also implements the externally visible {@link com.sun.tools.internal.xjc.api.ErrorListener}
aoqi@0	53	* so that we can reuse our internal implementation for testing and such.
