027 * The mechanism by which the value of the property can be initialised.

030 * This differs from the {@link PropertySetterFacet} in that it is only called
031 * when object is set up (after persistence) and not every time a property
032 * changes; hence it will not be made part of a transaction.
033 * 
034 * <p>
035 * In the standard Apache Isis Programming Model, corresponds to invoking the
036 * mutator method for a property.
