Not sure if anyone is doing this (or has thought about it), but it seems
to me that if one included a reference (URI) to an instance of an OWL
class (or property of a class) then that can be a step in the right
direction. 

So perhaps one could have:

<Name owl-ref="www.someuri.com">Peter Smith</Name>

where "owl-ref" (attribute name simply chosen by me for this response)
refers to an OWL class/property that conveys that "This is the full name
of a Person".
