You can export any subset of a method library as another in itself consistent method library. To that create a method configuration (see Creating a New Method Configuration) and then use the procedure described below to export this configuration as a method library. All references to other elements outside of the method configuration will be removed for the export to create a standalone in itself consistent library. The export will scan all elements of the method configuration and will also export all resource files, including images, documents, and templates.
In addition to exporting the method configuration, you could simply export a method configuration specification file that you want to share with other users. In other words, a file that defines a configuration, but does not contain the elements that are part of the configuration itself.
