Question : type of something in SAM
* Topic may have a type
* Occurrence may have a type
* Association may have a type
* TopicName may have a type (new with SAM)
* AssociationRole may have a type (new with SAM)

In 5.1 Type-instance relation, you describe a PSI
(http://psi.topicmaps.org/sam/1.0/#type-instance
<http://psi.topicmaps.org/sam/1.0/#type-instance> ) for special association
"Type-instance".
Is the [type] relation in SAM model a sort of syntactic shortcut to express
the same thing (like InstanceOf in XTM)?
