RE: Fallback mechanism for the datatype

[James Clark <jjc@jclark.com>]

If a RELAX NG implementation supported only the built-in datatype library, 
then it would be useful only for structural validation.  This is still 
useful functionality: XML 1.0 DTDs provide almost nothing in the way of 
datatype validation.  Applications might have some other way of doing 
datatype validation.  Requiring RELAX NG implementations to support at 
least one datatype library is pointless: an implementor can just make one 
up that contains just a "string" datatype.
