	Sure, but in a turn of Seaman-esque logic, since most (of those
	who have responded on this topic) view them as useful, then I
	guess they will go in.

	How one uses the term really isn't relevant to the discussion. 
	Taking from the parable, while the blind men all describe the 
	elephant differently, they agree that it is an elephant. 

	At any rate, I think you have really missed the point. All we 
	are looking to do is identify the meaning of the term , *in the 
	context of the IVOAT*, so that we catch any problems in orthogonal, 
	duplicate meanings (the "Coma" example having come up a couple 
	of times to illustrate the nature of the problem).

	Please get away from trying to argue we don't want to create a 
	traditional dictionary which has an effective domain of "everywhere". 
	We all agree we don't what to do that (I think). But that is *not* the 
	exercise we are discussing here, which is to short out duplication in
	means between tokens in a restricted domain (the IVOAT).

	At any rate, you have already agreed that:

	1> we put in short definitions to the vocabulary as time allows,

	and 

	2> definition work will not hold up a draft

	So I don't see the problem you have then with this part of the project
	(unless you are feeling that you will be compelled to write definitions 
	or edit them. Is that the case? Great!).

	I have already spent more time, defending every possible aspect of 
	trying to do this, that I could have probably put in a good 500 or so
	definitions and sorted out some degenerate tokens. THAT would be
	productive, this discussion/argument is quickly becoming otherwise.

	How about this, *lets stop discussing this*. Could we vote on whether 
	to do this (add definitions) or not? I think my vote is clear in this matter.

	Regards,

	=brian
