         An Annotation is a piece of information attached to a certain region of a text document. New kinds of annotations may be defined using this extension point. Annotations are attached to documents via their annotation model and may be displayed in text editors and views.

Annotation types form a hierarchy: an annotation type may refine another type by specifying it in its &lt;code&gt;super&lt;/code&gt; attribute.

Some annotations serve as the UI counterpart of markers (see &lt;code&gt;org.eclipse.core.resources.IMarker&lt;/code&gt;), while others exist on their own without having a persistable form. The mapping between markers and annotation types is defined by the optional &lt;code&gt;markerType&lt;/code&gt; and &lt;code&gt;markerSeverity&lt;/code&gt; attributes.
