How can we use android: inputType in EditTextPreference?

Question

I checked the documentation of EditTextPreference http://developer.android.com/reference/android/preference/EditTextPreference.html

But I could not find the android: inputType attribute there. Then how can this be used in this code segment

<EditTextPreference
        android:key="edit"
        android:title="@string/location1"
        android:summary="@string/summary1"
        android:dialogTitle="@string/location1"
        android:dialogMessage="@string/message"
        android:inputType="text"
        android:singleLine="true"
        />

The same doubt for the android: singleLine attribute.
