Fix NPE I found when using xu:message with an xpath that returned a set of attribs. Was another instanceof mess.  Code was something like if (  x instanceof 1ofNPossibleTypes ) { init } else if (  x instanceof 2ofNPossibleTypes ) { init } else if ( x instanceof 3ofNPossibleTypes ) { init }

if (  x instanceof 1ofNPossibleTypes ) { init }
else if (  x instanceof 2ofNPossibleTypes ) { init }
else if ( x instanceof 3ofNPossibleTypes ) { init }

So if unexpected type came in at runtime you'd get an NPE. ( Cause no init )
