nit: Drop "Extract" from the name?  Sounds kind of like the callback is expected
to do the extraction, which isn't right.

Done. Now it's called FormFieldDataCallback.

 
 // RenderWidgetHostView is an interface implemented by an object that acts as
 // the "View" portion of a RenderWidgetHost. The RenderWidgetHost and its
 // associated RenderProcessHost own the "Model" in this case which is the
 // child renderer process. The View is responsible for receiving events from
 // the surrounding environment and passing them to the RenderWidgetHost, and
 // for actually displaying the content of the RenderWidgetHost when it
 // changes.
