> Currently, the ResourceDefinition does not provide a good way to configure a child resource as mandatory or even its cardinality. Instead of that, manual validations are required inside handlers.
> The idea is remove manual validations and let it be done automatically by the model.
> Considering the following example:
> {code:xml}
> <parent-resource>
>     <child-resource/>
> </parent-resource>
> {code}
> Would be useful if we could mark the 'child-resource' above as mandatory. Or even:
> {code:xml}
> <parent-resource>
>     <child-resource/>
>     <child-resource/>
>     <child-resource/>
>     <child-resource/> <!-- This is invalid. Only 3 childs are supported. -->
> </parent-resource>
> {code}
> Where we can specify the cardinality for a child-resource so we can configure the min/max occurrences.
> I think the latter approach is more flexible and can be used to get a resource as mandatory or specify its number of occurrence.
