I am afraid that parsing these new tags would be difficult so we would 
need to define new attributes and values in the disambiguator; but it 
would be difficult to specify those in the rules as rules are written in 
static XML so they cannot use a construct that is defined outside the 
schema, and we'd need to modify the schema. But as we would retain the 
old postag interface (I think this is a must!) this would not be a problem.
