Hi, Thomas,
It's hard to promise a strict closed set for this use case, since 
describing concepts that are mentioned in text is as open domain as it 
gets. What we can reasonably require is the following:

- the concept should be dereferencible so that additional information 
about the concept available, either via a URI or via an XPath expression 
(or via a XPath expression to the URI); Here, we can at least have some 
idea of what is well-formed.
- in the case of terms, the users should point to the terminology 
lexicon that defines the list of terms; Here, we can actually validate 
the values.
- in the case of named entities, there may be only one type;
