    public interface IPluginFormElementTemplate
extends IFCPlugin
    Interface for plugins that wish to provide custom template for the form designer. Form templates are shown in the left drawer panel of the form designer. Users can add templates to their forms.

    In contrast to catalog plugins, a form element template may be a container that contains multiple elements.

    See also IPluginFormElementTemplate for more details.

    If you only want to provide static templates from the plugin's class path (e.g. src/main/resources, see IPluginFormElementTemplateStatic.

    A simple plugin with in-memory data (don't do this!) that provides two templates might look as follows: 

     import java.net.URI;
 import java.util.Map;
 import java.util.Set;
