This is a very good example of when attributes are optimal.
In this case, the attributes are object properties,
rather than children of the object.

Even so, a RECTANGLE element could use containment
to better advantage for cases where there are many,
possibly disjoint name/value pairs or collections.

<RECTANGLE>
<ORIGIN><X>0</X><Y>0</Y></ORIGIN>
<SIZE><DX>7in</DX><DY>9in</DY></SIZE>
<LABEL>My Pretty Rectangle</LABEL>
<IMAGE>floral.jpeg</IMAGE>
<BACKGROUND>gold</BACKGROUND>
<FOREGROUND>blue</FOREGROUND>
<FORM><SUBMIT/></FORM>
<ETC>...</ETC>
</RECTANGLE>
