Arvola, Case (b) and (c) can be differentiated by the presence of the perMessageDefault attribute. In other words, the attribute is optional with no default. The absence of perMessageDefault indicates that perMessage semantics are not in force. However, your point is well taken. A third option of notApplicable as an implied default would make the meaning of an absent perMessageDefault more clear. b ============================================ Bruce Pedretti Hewlett-Packard Company Software Developer 6000 Irwin Road (856) 638-6060 Mt.
