The ADL spec (section 4.3.3) says that
"with no cardinality, the meaning is that each child object
constraint of the attribute in question is a possible
alternative for the value.."
i.e. that this attribute is "single-valued" and the
types are multiple alternatives.
It then gives an example and says
"here, the cardinality of the value attribute is 1..1
(the default), which the occurrence of both QUANTITY
constraints is optional..."
I just wanted to confirm that the selection between
single-valued and multi-valued is dependant on the
_absence_ of a cardinality definition, not on whether
the cardinality is 1..1. So for a single value attribute,
it is actually illegal to put the "cardinality matches {1..1}"
in the archetype definition??
