Yes, that is the kind of solution I have thought of at first: including an 
additional table (or a link to it) with the relevant information in, for 
instance, html format.

I just wondered if there were some other more standard way in some data 
model, vocabulary, ontology (or whatever) fashion. And if somebody (other 
than me) is interested in it. It seems surprising that many people are 
interested in the meaning of fields, their descriptions, their relations, 
but not in how they should be displayed.

Yes,I understood it in the same way than you (although I only have read 
part of the conversation)

Thanks :-)
