/*
Not all fields defined by this type are initialized when it is created.
Some are initialized only when needed.

Accessors have been provided for some public fields so all TypeBindings have the same API...
but access public fields directly whenever possible.
Non-public fields have accessors which should be used everywhere you expect the field to be initialized.

null is NOT a valid value for a non-public field... it just means the field is not initialized.
*/
/**
 * OTDT changes:
 *
 * STRUCTURE:
 * What: support team package (cf. ReferenceBinding.maybeSetTeamPackage()).
 *
 * What: allow adding methods (for callout-to-field)
 *
 * READ FROM BYTE CODE:
 * What: restore predefined confined types.
 * Why:  + Synthetic flag is not set in the byte-code
 *       + Team.Confined has NO superclass.
 *
 * What: initialize AccRole, model, _teamModel and roleModel
 *
 * What: Read some information that normally would be skipped:
 * Which:+ Local types (plus set enclosingType, see LookupEnvironment.enclosingRole)
 * 	     + Synthetic methods of teams and roles
 * Why:  Need this info for copy inheritance.
 *
 * What: Evaluate OT-specific byte code attributes
 * How:  During cachePartsFrom call
 * 			+ ModelElement.evaluateAttributes(..),
 *          + AbstractAttribute.evaluateFieldAttributes(..) // only if fields are built
 *          + AbstractAttribute.clearReadAttributes()
 *
 * What: For methods: register(store) byte code, evaluate attributes (maybeRegister())
 *
 *
 * What: A ROFI intermediate patch for parsing a role file of a binary team.
 *       Source roles should always be compiled together with their team!
 * 		 FIXME: This patch is only used to detect source role in binary team,
 *              which must be strictly avoided any way.
 *
 * RESOLVE:
 * What: Methods/fields wrap types in signatures, link tsupers to their source.
 *
