                                    ^^^^^^^^^^^^^^^^^^^^

Actually, my comment was more about consistency with /OWL 1/ and RDF. 

Concerning XML Schema, being consistent with this standard looks to me more as "nice to have" than to be a requirement. Our notion of a datatype or a datatype map is not totally dependent on that of XSD, and we even define datatypes outside the scope of XSD (rdf:XMLLiteral, owl:rational).

But when I look into the XSD spec at

  http://www.w3.org/TR/xmlschema-2/

I can see that this document uses /two/ different terms: 

  * "lexical form" (e.g. in §3.2.16), and

  * "lexical representation" (e.g. in §3.2.17.1).

I'm not an XSD expert. Does anyone know whether these terms are used as synonyms? In this case, things would be especially fine for us. 
  
Nevertheless, I think we should not refer to XSD to motivate our step to change the terminology. It should be sufficient to point to OWL 1 and RDF. And these two specs say "lexical form".

Yes, of course!

Best,

PS: Apart from the somewhat hairsplitting discussion above, I, as the original commenter, would be happy with the outcome to use "lexical form". :)
