Indeed. However, it suffers from one glaring defect, which may simply  
be a problem of documentation: i does not explain its terms. In  
particular, it refers to a 'factor' of an event, without anywhere  
saying anything, either in the axioms or in the documentation, to  
explain what this strange term is supposed to mean. It is not normal  
English usage to refer to a 'factor' of an event, so ordinary English  
usage is no guide. The documentation at
http://motools.sourceforge.net/event/event.html#term_Factor
says  an event:Factor is 'everything used as a factor in an event',  
which is completely useless as it provides no explanatory information  
whatsoever. If an explanation of event:Foodle was that it described  
all the foodles of an event, that would be similarly useless as  
documentation. Can you say WHAT YOU MEAN by a 'factor'? If that is too  
much to ask, can you give some EXAMPLES both of factors and of non- 
factors of an event? It is not enough to only give examples, as this  
does not help the reader understand the limits of your conceptual  
idea. For example, can something be both and agent and a factor in an  
event? (Can you say, briefly, why or why not?) And so on. I know this  
is not easy, and it may be impossible to give a 'definition' of the  
term, but surely you can give SOME guidance to the user, if you are  
claiming that this is so simple and obvious to use in such a wide  
range of applications.

RIght now it is impossible to grasp, and I would have no confidence  
that any two extensions would be consistent.
