Internals
Internals
This template itself only determines which sort of information request is being made, and either provides the information (if it isn't asking for a full subject display); or delegates the request to {{root subject/core}}, which is responsible for generating a full display. Delegation is done using Module:TScope#override, so that the subtemplate can tell which parameters were not provided, in order to supply default values for them.
When the transcluding page is in Subject: or Template: space, this template always delegates to produce a full display. In all other namespaces, ordinarily the template returns a string describing the parentage of the subject. The general form of the parentage string is described at {{subject page}}; here the string provided is fixed, there being no actual parent parameters by which to vary it, as /Books by subject/ — thus presenting each root subject as a child of single parent Subject:Books by subject. (Subject:Books by subject also uses this same parentage-string scheme, presenting itself as having no parents, i.e., //.)
Parameters 1 and 2 function as described at {{subject page}}.
