The School API documentation for School.Model.RelationshipRead.Contact describes the returned value incorrectly. See attached image 001. The tooltip is shown by SKYLib. They said that the tool-tip comes directly from a Blackbaud file.
The documentation says that Contact "Returns True if No Contact is enabled in the UI." My testing shows that it returns FALSE if "No Contact" is enabled. Given the name of the field in the UI and the name of the field in the API, I believe that the return value is correct and the description in the XML file is incorrect.
These screenshots come from a test program that uses SKYLib. Protégé says that the tool-tip text is coming from a XML file produced by Blackbaud.
