In addition to whatever datatype components may be built in, one of the use 
cases we discussed was one in which an XHTML editor might have built in 
knowledge of a schema for XHMTL. Nothing precludes a special-purpose editor 
of other industry standard vocabularies from building in knowledge of the 
validation rules for those vocabularies.
