Once these steps are taken you may run your application, create documents and Save/Open them. These resource files already exist in the OCAF (format "Standard").
-If you use your specific attributes from packages, for example, <i>P-, M-</i> and *TMyAttributePackage* (see @ref occt_ocaf_3_4_6 "Specific attribute creation") you must take some additional steps for the new plugin implementation:
+If you use your specific attributes from packages, for example, <i>P-, M-</i> and *TMyAttributePackage* (see @ref occt_ocaf_3_5_6 "Specific attribute creation") you must take some additional steps for the new plugin implementation:
1. Add our *P* package to the standard schema. You can get an already existing (in Open CASCADE Technology sources) schema from *StdSchema* unit and add your package string to the cdl-file: package *PMyAttributePackage*.
2. The next step consists in the implementation of an executable, which will connect our documents to our application and open/save them. Copy the package *PAppStdPlugin* and change its name to *MyTheBestApplicationPlugin*. In the *PLUGIN* macros type the name of your factory, which will be defined at the next step.
