Sql Developer Data Modeler 3.0 EA1: Custom transformation script

Question

What is the object model used by:
Tools -> Design Rules -> Transformations
From looking at the examples (and guessing) I have managed to create ID attributes on all my entities, but how do I set its sequence number or set it as the primary key?
entities = model.getEntitySet().toArray();
for (var e = 0; e<entities.length; e++)
entity = entities[e];
att = entity.createAttribute();
att.setName('ID');

Answer 1

content of XML files:
1) class described, parent class if there is one
2)<property .../>
describes property - set and get method, data type of property, default value
3) <collection ... />
describes collection of objects belonging to class - 5 collections are defined in Table.xml - columns, indexes, table check constraints, column groups and spatial definitions
- get method - to get collection
- create item method - method of described class used to create item for that collection; so for columns collection table.createColumn() will create column in table
- other methods - add, move, remove if are defined
4)other meta data
definitions in 1) .. 4) are used by Oracle SQL Developer Data Modeler, so it'll be wrong to modify those xml files
5)<roproperty ../>
Data Modeler doesn't parse/process these definitions, we decided to not filter them out however you should not rely that much on them
6)some junk left
For each object you can set your own properties and they will be persisted (also included in compare/merge in versioning) together with other information for object - look at "template table" example in transformation scripts. Here are methods you can use:
void setProperty(String key, String value);
     String getProperty(String key);
     boolean hasProperty(String key);
     boolean hasProperty(String key, String value);
     void removeProperty(String key);
     void clearProperties();
     Iterator getPropertyNames();
