What is the objective you are trying to fulfill with this?
You need to have a parent component which should act like parsys(container) of other component but I doubt then parent component will have any authoring then.
If you just want to extend you can use sling:resourceSuperType property in child component to inherit parent component.
Thank you for the response.
The objective is go through every Component inside of a Page looking for an attribute in each component.
Looking at the information inside of jcr:content of the Page, I can recover different components, but there is components included in the page component as the Top Navigator that does not appear its information in jcr:content of the Page.
For that I need to know if exists any possibility to achieve this information, looking the components included in other components.
The attribute is in the Component inside in /apps.
