Actions on a structural feature that is also an association end has the same semantics as
the actions on links. Clarify as below.

"If the structural feature is an association end, then actions on the feature have
the same semantics as actions on the links that have the feature as an end. See
specializations of StructuralFeatureAction."
In ReadStructuralFeatureAction, Semantics, after first sentence add:
"If the feature is an association end, the semantics is the same as reading links
of the association with the feature as the open end."
In AddStructuralFeatureAction, Semantics, at end of first paragraph, add:
"If the feature is an association end, the semantics is the same as creating a link,
the participants of which are the object owning the structural feature and the new
value".
In RemoveStructuralFeatureAction, Semantics, at end of first paragraph, add:
"If the feature is an association end, the semantics is the same as destroying
links, the participants of which are the object owning the structural feature and
the value being removed."
In ClearStructuralFeatureAction,
"If the feature is an association end, the semantics is the same as
ClearAssociationAction on the object owning the structural feature."
