Why doesn't style="@android:attr/listSeparatorTextViewStyle" cause error? -

i think following code cause error, think android system lib doesn't exist style named listseparatortextviewstyle in styles.xml. code doesn't cause error, why?

<textview  android:id="@+id/dialog_title"     android:layout_width="match_parent"     android:layout_height="wrap_content"      style="@android:attr/listseparatortextviewstyle"   /> 

the code doesn't show error because listseparatortextviewstyle. take @ this. have tried up?
