// This is a derivative of the framework abstract class which defines the
// interface to a list of attribute defs that belong to a particular
// element. The scanner needs to be able to get a list of the attributes
// that an element supports, for use during the validation process and for
// fixed/default attribute processing.
//
// Since each validator can store attributes differently, this abstract
// interface allows each validator to provide an implementation of this
// data strucure that works best for it.
//
// For us, we just wrap the RefHashTableOf collection that the DTDElementDecl
// class uses to store the attributes that belong to it.
//
// This clss does not adopt the hash table, it just references it. The
// hash table is owned by the element decl it is a member of.
