About the Wiki Discussion category

This category is for use only with the Wiki category.

When a Wiki topic is created, a Wiki Discussion topic is also created so that the Wiki topic will have only one post and hold the content. The Wiki Discussion allows for multiple post to discuss the Wiki topic.

What is the definition of “Wiki category”? I also find a category " SWI-Prolog web site and services". But I wonder whether there is a category “Documentation”.

Are “Documentation” question that refer to an error or a gap on the SWI-Prolog web site manual sections supposed to go into the “Wiki category”. Or is there a specific category for it?
