Attributes

def

[EBNF] The def attribute contains a URI reference that points to a production where the nonterminal is defined.

Note that this is not an IDREF, it is a URI reference (as, for example, are href attributes on HTML a elements). This is necessary because references to non-terminals might need to cross document boundaries.
