[Clas_hadron] DNP abstract

[burkert]

In my opinion, this abstract on the Omega- is quite premature. It talks 
about "we will analyze".  What is the point of submitting an abstract 
before even a hint of Omega- events is seen in the data? At least I 
haven't seen any of it. It is bad practice to submit abstracts based on 
unsubstantiated projections that later have to be withdrawn or results 
in a no show. We have to show data that have clear impact.
