I noticed this within the person model (Didn't pick up on it the first time):
<associations>
<association name="cm:avatar">
<source>
<role>cm:avatarOf</role> <!-- What is the purpose of this?? -->
<mandatory>false</mandatory>
<many>false</many>
</source>
<target>
<class>cm:content</class>
<role>cm:hasAvatar</role>
<mandatory>false</mandatory>
<many>false</many>
</target>
</association>
</associations>
I am duplicating this association for my own model and would like to know it's significance of this element within associations.
