Every extension defines a set of standard parameters that enabled d3web to use the extension well. Depending on the extension point, there might be additional parameters. The most frequently parameters are as following:
|| Parameter || Description
| class | Defines the class that is used to instantiate the extension's implementation. The class denoted here must implement the java interface that belongs to this extension point. Please note that most extensions will be instantiated by their default constructor.
| name | A unique name of the extension in this plugin.xml. Usually the name shall be unique at all, but this is not necessarily required.
| description | A brief description of the plugin. The description is in some cases also used to be displayed to the user, so use them carefully. Simple html markups are allowed to be used in the description (such as <b>,<br>,<code>,<ol>,<ul>, ...)
| version | Version of this extension implementation.
| priority | The priority of the extension within the same extension point. The lower the number, the more the extension is prioritized.
| scope |
!! Working with Priorities
The priority of the extension is a number compared to all the other priorities within the same extension point. The lower the number, the more the extension is prioritized. Most extensions use 5, but always use a number between 1 and 9. Fractional numbers are allowed.
The priority defines the order the extensions are considered by the specific extension points. Depending on the extension point different priorities may lead to completely different results. See the table below to get some idea how priorities will effect the behavior:
|| Extension Point || Effect of Priority
| Renderer | For a specific section type (based on a matching scope, see below), only the renderer with the highest priority is selected to render the section. With more prioritized implementations you can redefine the rendering of a wiki page.

! Scope for Renderer
For the interface [Renderer|https://isci.informatik.uni-wuerzburg.de/javadoc/KnowWE/de/knowwe/core/kdom/rendering/Renderer.html] scope defines which type should be rendered by the Renderer. The example below defines, that the root section (the whole wiki-page content) is rendered by an instance of the class RootTypeIdRenderer.
