> If you have this definition in CIMI model (MachineTemplate in this case):
> array :volume_templates do
>   ref :volume_template
> end
> and you use this JSON in .from_json method to create an instance of the MachineTemplate:
> <snip>
> 'volume_templates' : [
>   { 'volumeConfig' : { 'capacity' : '12345' } }
> ]
> </snip>
> The resulting 'machine_template.volume_templates.first.volume_config.capacity' will be
'nil'.
> I tried to play a bit with the input JSON and I found that if you use this:
> <snip>
> 'volume_templates' : [
>   'volume_template' : {
>     { 'volumeConfig' : { 'capacity' : '12345' } }
>   }
> ]
> </snip>
> The resulting 'machine_template.volume_templates.first.volume_template.capacity' is set
properly to '12345' :-)
> The XML output then looks like:
> <snip>
>         <volumeTemplate>
>           <volumeTemplate>
>             <volumeConfig>
>               <capacity>10240</capacity>
>             </volumeConfig>
>           </volumeTemplate>
>         </volumeTemplate>
> </snip>
> I think we need to do something smart in the 'array' to remove the upper 'volumeTemplate'
or introduce something like 'ref_arr :volume_templates'.
> Anyway, I'm leaving this one to you David, as you might have better schema knowledge
than me ;-)
