I've been noticing superfluous changes in my xib files with Interface Builder 3.2.1.

Here are a few of them:

-   			<reference key="NSNextResponder"/>
+   			<nil key="NSNextResponder"/>


-   			<reference key="NSSuperview"/>


-   	<array class="NSMutableArray" key="IBDocument.EditedObjectIDs">
-   		<integer value="6"/>
-   	</array>
+   	<array class="NSMutableArray" key="IBDocument.EditedObjectIDs"/>

Can anyone tell me what these are, and are there any tricks for avoiding them? I'd prefer my checkins to only describe changes I intentionally made.

Update: I wasn't clear in the original question, but these differences were caused by opening the file in Interface Builder and saving it without making a change.
