This is considered in the paper "Extending VOEvent for more complex 
data", with a number of examples, at
http://www.ivoa.net/Documents/Notes/VOEventTables/20100323/

The answer is that you can always link the remote data, but sometimes it 
is good to be able to send simple data along with the message packet 
itself. In the past this meant Param and Group of Param. The note 
suggests that an extension to Table is not difficult to parse and yet 
much more expressive.
