The intent here is that E and V are free variables in a definition: it's defining a function 

function has-id-value(E, V) {
  is-id(E) and data(E) eq V
}

Perhaps it would be clearer to the typical reader if it were done in pseudo-code rather than legalese English.

I think this is all that would be necessary:

   E has an ID value equal to one of the candidate IDREF values, V, where:
