Question about example in MathML2 Spec (Second Edition)

Hello,

I am wondering that the rendering example of 3.4.6.2 (image/3022.gif
and 3023.gif) of MathML2 Spec (Second Edition) is not correct.

In these examples, 0(underscript) and &infin;(overscript) are 
positioned as superscripts and subscripts. Is this correct ?

The Spec says at 3.2.5.9 Other attributes of mo as follows:
---------
The movablelimits attribute specifies whether underscripts and 
overscripts attached to this mo element should be drawn as subscripts 
and superscripts when displaystyle="false". movablelimits="false" 
means that underscripts and overscripts should never be drawn as 
subscripts and superscripts. 
---------

The default value of movablelimits is set by operator dictionary.
But operator dictionary for &int; is specified as follows:

---------
"&Integral;" form="prefix"  largeop="true" stretchy="true"  lspace="0em" rspace="0em"
---------

The value of movablelimits is set as "false" depending on the 
description 3.2.5.2.

Finaly, 0(underscript) and &infin;(overscript) should be not be drawn 
as superscripts and subscripts.

Is there any misunderstanding ?
