Protected Associations and Protected Methods
You can model association relationships in the BII, and you can model methods in the BII for which no corresponding method exists in the BID. See the LN Studio online help for more information.
When generating an LN implementation, protected methods will not only get a protected interface in the generated 'st' library, but also an XML-based interface in the generated 'sb' library. You can forward a request XML from a public method to a protected method
