    What we all agree on is that we don't want to try to define a plain-text
    rendition of 2D diagrams. However, there exist in-line versions.

    Something of the form


    in contrast to


    would definitely fit the definition of in text use. For music, we've
    even coded the symbols so they can be cited (in isolation from musical
    scores) in text. I've definitely seen examples of texts showing
    distinctive symbols in running text when discussing 2-D structure diagrams.
    Such use would be analogous.

    representative publications.
