Good to know that my friends understand me :-) Actually, this is a very 
basic decision we have to take: what LexicalEntry is meant to be? From one 
of our latest calls, I got the impression that this concept should not be 
used for characterising 'tokens' (e.g. lexical occurrences into texts), 
but rather 'types' (e.g. lexemes) into lexical resources, such as 
dictionaries. To me, there's a striking difference, since you can 
predicate very different properties on the two kind of entities. For 
instance, lexical occurrences (token) are usually grammatically 
determined, while lexical entries in a dictionary (type) may leave many 
grammatical attributes open (including the 'word class', in some case).

Not at all, I think that in ordinary speech there are many lexical senses 
that do not commit to anything :-)

Anyway, this is a very technical question. In the current model, the 
ObjectProperty 'reference' ranges to 'Reference' (by inheritance from 
'isConceptualizationOf'). Should we opt for breaking formal links to other 
ontologies (semiotics.owl in this case), as I warmly recommend, how we 
could characterise the range of this very basic property?
