VOEvent v2.0, some thoughts

[Rob Seaman]

I see this as a section in the users guide.  Other options would be  
XSLT and XQuery.  While STC provides the obvious crying need for such,  
flexible manipulation of <What> and <Why> elements will ultimately  
prove more interesting from the point of view of empirical use cases.
