Type Tree Errors 
Each card in the map specifies a type and a type tree. Type trees referenced by 
the map must be analyzed and saved. If you build a map, and a type tree 
referenced by that map has not been analyzed, or it has been analyzed but 
produced at least one error, an error message to that effect appears. For example, 
if the type tree address.mtt was not successfully analyzed and it is used in a 
map, building that map causes the following message: 
You are not prevented from building the map. However, you may get 
unpredictable results when running the map. For example, if a group’s 
components are not distinguishable, it is not clearly defined where one component 
ends and the next one begins. The data may not validate correctly. 
Note  A type tree that has not been analyzed as error-free includes the following: 
♦  A type tree that was analyzed and produced at least one error. 
♦  A type tree that has been analyzed, but not saved.
