[WikiEN-l] Templates and old page versions

[Carcharoth]

I think I've asked this before, but I'm raising it again as I've
noticed templates being used again within articles to allowed finer
control over specific parts of article content. This practice of using
templates within articles for the actual text of articles is something
I think should be discouraged because it messes up page histories and
makes it difficult to work out who edited what on a page.

The question I have is whether it is possible for old page versions to
display warnings that if templates were on the page, that the content
from that part of the page comes from current templates, rather than
showing what was originally there when the page was published.
Currently there is a warning on top of old page versions that says
"This is an old revision of this page, as edited by XXX at YYYY. It
may differ significantly from the current revision." But that doesn't
go far enough, IMO. There needs to be a warning included there that
images and templates may display as red-links if subsequently deleted,
or may display content different from what was originally there if
later updated, or may display something completely unrelated (if a
template is deleted and recreated or re-coded, or the image
overwritten with a new image).

Does anyone know which mediawiki page produces that warning, so I can
suggest changing it?
