Re: XML Schema WG's comments

A "process" comment... I note that the first URI is not publicly readable 
(W3 member access is required).  I think all the same information is 
available at the second URI.

With reference to Concepts-related comments:

2.1 They suggest the term "lexical mapping" instead of "datatype 
mapping".  I see no problem with that change.

2.2 Suggestion to restrict the value space to those values for which there 
is a lexical form.  I cannot identify any problem with this, but I'm 
uneasy.  I think it means that applications designers must be aware of the 
allowed lexical forms whenever using a datatype name as a class name in 
RDF.  I wonder if there is scope for surprises here?

2.3 Suggests describing the lexical space of datatypes as being "character 
sequences" rather than "strings", to reduce possibility of confusion with 
the datatype called "string".  I think the suggested change is fine.  (But 
I do find myself wondering if the tail is wagging the dog here;  there is 
this common problem that when certain terms get specific technical 
interpretations, we are pressured to stop using them for their more common 
purpose.  The term "model" springs to mind.)

2.4 Language tagging of strings is not enough for encoding natural 
language.  I think this warrants discussion.  I think a number of people 
(including myself) are uneasy about the special treatment of language tags 
when there may be more elegant and comprehensive ways to achieve the 
desired goals.

2.5 Editorial. Noted.
