Template:Subject category/core2/doc

This template implements the final phase of internal processing for template {{Subject category}}. On entry here, we already know the subject page exists and is correctly formatted for extraction of its parents, and we have already extracted its parents.

Usage

There are three parameters, assumed to be specified (even if blank).

• parent — the name of a parent subject, or blank.
• parent2 — the name of a parent subject, or blank.
• subject — the name of the subject associated with this category.

This template generates the category header for this category, and adds this category to its parent category(-ies). The form of the category header depends on what additional information, if any, is provided by the subject page.

Internals

Availability of additional information from the subject page is determined by transcluding the subject page with template parameter 1=mode. If the subject page responds with header, the full content for the category header is expected to be available by transcluding the subject page with template parameter 1=header, and this is done. If the subject page responds with description, a description of the category is expected to be available by transcluding the subject page with template parameter 1=description, and this is done and the result is appended to the default category header. Otherwise the default category header is used.
