Ah!  Thanks.  I missed that somehow when the discussion immediately  
moved back to DM considerations.  It's not quite as concise as the  
napkin model, but not too bad.  This example undoubtedly doesn't  
cover the full range of VOTable flavors that could be returned in  
response to different queries.  To support this we would likely be  
obliged to add full VOTable support.

A productive avenue might be to combine a simple native VOEvent time  
series element to cover the proverbial 90% of the cases, and  
encourage using <References> to external SSA compliant VOTables for  
the more demanding 10%.

A goal with this and the other semantic improvements to VOEvent that  
are on the table, e.g., orbital elements, would be to demonstrate  
compatibility with GCN (that Scott is already doing and others have  
tackled before), and with other such services as SNEWS (ditto Kate),  
but also with various types of natural language publications such as  
CBAT, MPC and ATEL.
