please find enclosed a version of the pinger schema without  
dependence on the ping schema - as per requested.

i still need to know about whether the <select:parameter/> can or  
even should be used to interrogate the contents of the <nmwg:datum/>  
elements. if i can, for example to request all pinger xml's results  
with meanRtt < 5.0 then i have no need to have the pinger statistical  
results in the metadata block.

the other question is whether pinger should in fact be just a  
transformation service, rather than a MA or MP. such that it would  
know about Ping MA's and basically proxy requests. however, it would  
probably need to maintain it's own local cache for speed purposes -  
which in effect would make itself an MA... does this make sense?

Cheers,

Yee.
