A.4.1 Definition of Support
A DSA implementation may be an invoker and/or a consumer of a DSA operation unless 
Chaining Mode is supported, then the DSA implementation must be able to invoke and 
consume DSA operations.
A capability is said to be supported if the Implementation Under Test (IUT) is able:
•
to generate the corresponding operation parameters (either automatically or because 
the invoker requires that capability explicitly);
•
to interpret, handle and when required make available to the invoker the 
corresponding error or result.
A protocol element is said to be supported for a sending implementation if the IUT is 
able to generate it under some circumstances (either automatically or because the 
invoker requires relevant services explicitly).
A protocol element is said to be supported for a receiving implementation if it is 
correctly interpreted and handled and also, when appropriate, made available to the 
invoker.
An object class is said to be supported if the IUT is able to construct entries of that 
object class.  Support of an object class also requires support of the object identifier(s) 
of its superclass(es) of that object class.
An attribute type is said to be supported by a DSA implementation if the DSA supports a 
subset or all aspects of the attribute syntax of the attribute and stores the attribute 
value(s) where appropriate.
