DVAL
expressions return dimension values.
DVAL CONST
expressions return the dimension value (or set
of dimension values), specified in
DIMENSION_ID/DVAL_ID
expression node pairs.
For example, using a
DVAL CONST
expression within a
VOID ADD_DVAL
expression instructs Forge to add the
dimension value to each record processed. The
DIMENSION_ID
and
DVAL_ID
expression nodes may be repeated in pairs to
create sets of dimension values. Forge then adds the set of dimension values to
each record processed.

EXPRESSION
element for DTD and attribute information.
