Chain ring vs catenary ring

The definition of "chain ring" and "universal chain ring" do not agree with the literature, or with the article at Chain ring, which consistently define a chain ring to be one whose ideals are linearly ordered. I think that what should be written here is " universally catenary ring" (or "catenarian"). Richard Pinch (talk) 18:54, 24 December 2014 (CET)
