Current text:
[[[
4. Use of schema-defined datatypes

   The datatyping proposal should not preclude using schema languages to 
define
   data types, rather than relying on "built-in" predefined data types.
   The proposal is not expected to give an account of any such schema language.
]]]


The meaning that I was trying to capture was much broader than that:

IF one has a schema language that can define datatypes
AND one uses that language to define the characteristics of some datatype
THEN the RDF datatyping scheme should not preclude the use of dada types so 
defined.

(This might include an RDF-based schema language for defining data types, 
if such an animal were to exist then that might be just one target for this 
desiderata, but not the only one.)
