An expression is defined as being abstract. An expression can currently use the concrete types, reference, sequence or encoding. The user is able to define new concrete expressions.

meta.expression: meta.abstract();

meta.expression#reference: meta.map( #meta.expression, #meta.reference );
meta.expression#sequence: meta.map( #meta.expression, #meta.sequence );
meta.expression#encoding: meta.map( #meta.expression, #meta.encoding );
