What is the difference between par base and parsys?
Par base :
* The par base allows components to inherit attributes from other components, similar to subclasses in object-oriented languages such as Java, C++, and so on.
* For example, when you open the /libs/foundation/components/text node in the CRX Explorer, you see that it has a property named sling:resourceSuperType, which references the par base component.
* The par base here defines tree scripts to render images, titles, and so on so that all components subclassed from this par base can use this script.
Phrases (Paragraph System) :
* The paragraph system (parsys) is a compound component that allows authors to add components of different types to a page and contains all other paragraph components.
* Each paragraph type is represented as a component. The paragraph system itself is also a component, which contains the other paragraph components.
