The hLS should be the only thing that summarizes what a service will 
register (gLS's just sumamrize what an hLS sends along).  The 
perfSONAR-PS instances currently recognize multiple eventTypes, multiple 
'supportedEventType' parameters, or several metadata blocks as you are 
sending.  If you would like a test instance please let me know.
