Thread:Extension talk:Cite/Number of references/reply (3)

Actually, I have the tag on almost any page, embedded as it is in a template so that I don't have to remind myself of adding it manually. When no references are used on the page, the list simply does not appear. The only nuisance is that I can't make the subheading (e.g. "References" or "Endnotes") conditional on the presence of tags. The subheading appears regardless.
