The specification of a annotation model factory. In order to find a factory for a given file the attributes of each factory specification are consulted in the following sequence: contentTypeId, fileNames, extensions. If multiple, equally specific factory specifications are found for a given file it is not specified which factory is used.

- class - a fully qualified name of the factory implementation class. This class must implement the `org.eclipse.core.filebuffers.IAnnotationModelFactory` interface.
- extensions - a comma separated list of file extensions for which this factory should be used
- fileNames - a comma separated list of file names for which this factory should be used
- contentTypeId - the id of a content type as defined by the `org.eclipse.core.runtime.contentTypes` extension point for which this factory should be used

###### Examples:

       <extension
          point="org.eclipse.core.filebuffers.annotationModelCreation">
          <factory
                extensions="xzy"
                class="org.eclipse.ui.texteditor.ResourceMarkerAnnotationModelFactory">
          </factory>
       </extension>
