[css3-images] image() notation and <img>

Can I write the following?

   <style>
     #myDiv {
       background-image: image('#myLogo');
     }
   </style>

   <div id="myDiv">....</div>
   ....
   <img id="myLogo" src="myLogo.png"/>

expecting the div will acquire the logo as background-image
or should the target of image() here be an image format?
I don't think the CSS Image Values and Replaced Content Level 3
spec is clear enough about this in section 3.2 and it probably
needs a clarification as a note or warning?
