the text displayed for a new numbering is **Category number** *(Title)* or **Category number**;
the link displayed for an automatic reference is Category number using the cite shortcut notation;
the entry in the table of contents is Category number (Category for LaTeX document) or Title.

These behaviors can be changed by adding metadata for a given category.
