[EXI] Will EXI Learn in Schema informed encoding ?

Hi John
    When the schema has wildcarded elements(any) we will add SE(*)
production to the corresponding grammar. When this event is matched by a
wildcarded element in the XML instance dont we need to learn the element by
making an SE(qname) entry for that element in the current grammar ? The
wildcard schema grammar semantics does not mention about this learning. 
    If we dont need to learn it, what is the reason for the same ?
