ITP uses include documents to re-use model document fragments and mechanisms in several model documents.
The ITP/MDK Repository supports the use of include documents. Folders in a project can be assigned to be include folders (on the tab Project of the projects configuration). Documents in such a folder can be included in all model documents that reside in the project (with the "__INC()" instruction; refer to the ITP Model language Help for more information on the ITP Language). When a document is included in a model document, its ITP instructions and text are available in that model document.
