markertype - The markertype is the id of the type defined in org.eclipse.core.resources.IMarker that this definition is applied to.
icon - If there is no class defined the icon attribute is used to define the icon that will be applied to this type of marker.

  <extension
         point=
"org.eclipse.ui.ide.markerImageProviders"
>
      <imageprovider
        markertype=
"org.eclipse.core.resources.taskmarker"

            icon=
"taskicon.gif"

            id=
"myPlugin.declarativeMarkerProvider"
>
      </imageprovider>
      <imageprovider
            markertype=
"org.eclipse.core.resources.problemmarker"
