Reference docs - include Component Subcomponent linking

[roleyfoley]

Expected Behaviour

When reading the reference site and I get to a Component I should be able to see the subcomponents it supports and be able to click a link to go to the Sub Component reference guide

Current Behaviour

There is no way to find the Sub Component configuration and the Key in the Component doesn't list the sub component collection

Possible Solution

When forming the schema create refs for between the sub component and component

Context

Understand all possible options for a component
