 /**
- * Annotation used to indicate a constructor parameter, field or method that is
- * used to inject a configuration property value.
+ * The @Property annotation is used to denote a Java class field,
+ * a setter method, or a constructor parameter that is used to
+ * inject an SCA property value. The type of the property injected,
+ * which can be a simple Java type or a complex Java type, is defined
+ * by the type of the Java class field or the type of the input
+ * parameter of the setter method or constructor.
+ *
+ * The @Property annotation can be used on fields, on setter methods
+ * or on a constructor method parameter. However, the @Property annotation
+ * MUST NOT be used on a class field that is declared as final.
  *
- * @version $Rev$ $Date$
+ * Properties can also be injected via setter methods even when
+ * the @Property annotation is not present.  However, the @Property
+ * annotation must be used in order to inject a property onto a
+ * non-public field.  In the case where there is no @Property
+ * annotation, the name of the property is the same as the name of the
+ * field or setter.
+ *
+ * Where there is both a setter method and a field for a property, the
+ * setter method is used.
