Questions about relationship multiplicity

[robertmarkbram]

I have two questions about multiplicity in relationships (Alfresco-Community-3.3).

First question: what does the source's mandatory attribute mean? It doesn't seem to make a difference whether I make it false or true.

<type name="yourCo:product5">
   <title>Product</title>
   <parent>cm:content</parent>
   <associations>
      <!– one to one –>
      <association name="yourCo:productGraphicLink">
         <title>Product Graphic</title>
         <source>
            <mandatory>false</mandatory>
            <many>true</many>
         </source>
         <target>
            <class>yourCo:productGraphic</class>
            <mandatory>false</mandatory>
            <many>false</many>
         </target>
      </association>
   </associations>
</type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Second question: is it broken to have target mandatory = true and many = true or do I just not understand it? My understanding is that you can't make an instance of the below unless you first have more than 1 instances of the target.

<type name="yourCo:product">
   <title>Product</title>
   <parent>cm:content</parent>
   <associations>
      <!– one to one –>
      <association name="yourCo:productGraphicLink">
         <title>Product Graphic</title>
         <source>
            <mandatory>false</mandatory>
            <many>false</many>
         </source>
         <target>
            <class>yourCo:productGraphic</class>
            <mandatory>true</mandatory>
            <many>true</many>
         </target>
      </association>
   </associations>
</type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But whenever I try to make this I get:
