Ok.  I just found where it does exist in ibiblio.  So no problems
there.   The dependency should be:

    <dependency>
    	<groupId>woodstox</groupId>
    	<artifactId>wstx-asl</artifactId>
    	<version>2.0.5</version>
    	<scope>runtime</scope>
    </dependency>

However, I just noticed that the tests only run properly if I compile
with Eclipse.   If I compile with Maven, then NullPointerExceptions
are thrown:

Any ideas on what might cause that?
