Wikipedia:Category header

This is a proposal to replace the current category headers with one standardised category header, possibly under the name Template:Category header. The proposed category header can be found at User:Mclay1/Category banner. Without any parameters it looks like this:

User:Mclay1/Category banner

The message box only appears if the template is transcluded outside of the category namespace.

This template replaces the following templates:
 * Cat main
 * Set category
 * Wikipedia category
 * Hidden category
 * Tracking category
 * Stub category
 * Parent-only stub category
 * Help category
 * Redirect category
 * All included
 * User category
 * Portal category
 * Other proposed/deleted templates

The template can be expanded to replace more templates if necessary.

The following examples demonstrate a few of the parameters but are otherwise nonsense.

Example:  produces:

really good articles

Example:  produces:

User:Mclay1/Category banner

Please discuss this template on the talk page. When discussing, please do not just vote on the proposal – it is a discussion. The pictures are probably not the best ones available. Please suggest better ones if you know of any.
