Declaration Syntax Return Valuetrue if the dimension is fully implicit, and
false if the dimenension contains any valid
refinements or a descriptor.

has no non-implicit refinements and has no descriptors.
That is, the dimension no longer has any refinments that
would narrow the size of the results set and has not had
any selections made to it.
