When a reference is first added to the page, the list of references at the bottom should be appended automatically using the format that is appropriate (usually <references />).
The purpose of this request is to make life easier for editors. Currently, when an editor adds a citation to an article using the <ref></ref> syntax, the citation is not visible to readers until the editor also manually adds the wiki syntax (usually <references />). Also, in order to create a title for the references section in normal article style, the editor needs to manually add ==References== above <references />. I do not believe there is any use case in which an editor would add a citation to an article, without also wanting to append the list of references at the bottom of the article. Therefore, I think the list of references should be appended automatically whenever a reference is first added to the page. This would save editors two rote manual steps.
