/**
* Creates an OID with a single attribute for the key. To create a multi-valued OID, use a single
* arg OID constructor, and add individual properties with the set method. This constructor should
* be used when the object type being instantiated has a single primary key. For instance, if the
* object type is <code>com.arsdigita.kernel.ACSObject</code> then the value should be the <code>
* object_id</code>. So, if developers wanted to create the OID for ID zero, they would call
* <code>new OID(acsObjectType, new BigDecimal(0))</code>. A <code>BigDecimal</code> is passed in
* because the "id" attribute for the ACSObject type is declared as <code>BigDecimal</code> in the
* PDL file.
*
* @param type The ObjectType of the ID
* @param value The value of the ID
* @exception PersistenceException will be thrown if the given object type does not have exactly a
* single key (if <code>type.getObjectMap().getObjectKey().getCount()
* != 1</code>).
* @pre type != null
* @pre type.getObjectMap().getObjectKey().getCount() == 1
