videoView XML file is showing error !

Error in the following XML :

 <?xml version="1.0" encoding="utf-8"?>
 <VideoView xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/videoView" 
     android:layout_width="fill_parent"
     android:layout_height="fill_parent" />

The error shown is : Multiple annotations found at this line: - The processing instruction target matching "[xX][mM][lL]" is not allowed. - No grammar constraints (DTD or XML schema) detected for the document.
