==Rationale==
===Use cases===
* Superscript
** Basic maths
** Units of measurement (e.g. square meter - m²)
** Large numbers, metric scientific notation (e.g. 1,253x10²³)
** Ordinal numbers (e.g. 1^^st^^, 2^^nd^^, 18^^th^^ century, in French 1^^er^^, 2^^e^^, 18^^e^^ siècle)
** Possibly for footnotes (shouldn't it be handled by another mechanism than what is considered, in that particular case, as a presentation markup)
** Many indexed terms in science (like n^^+^^)
* Subscript
** Basic maths
** Basic chemistry
** Much of biology (gene names, etc.)
===Alternatives===
* Unicode digits
* Specialized markup languages like MathML, ChemML and LaTeX
than as part of formulas.
===Advantages===
* Simple way to insert superscripted/subscripted text
* The users don't have to learn a new language.
* Super- and subscript are basic functions in most word processors
* Super- and subscript almost always have a semantic value, rather than being a formatting issue.
* Depending on the software/keyboard layout, it might be very difficult or impossible to insert Unicode superscript or subscript digits.
* Unicode digits:
** are limited to... digits! - thus covering only a small subset of use cases (⁽⁻ⁱ⁺ⁿ⁾⁼°ₔ₍ₐ₊ₑ₋ₓ₎₌ₒ)
** The presentation of successive Unicode digits is not always appropriate (see above of this source).
* MathML etc. is necessary for specialized applications, especially in Math. However:
** Complex formulas were historically expensive, and use in engineering and science therefore limited. Invention of symbols involving the no-cost super and subscript was much more frequent.
** In practive, MathML etc. is not currently supported, and does not correspond with the frequency of use of super- and subscript in engineering and science. LaTeX is, on the other hand, more common and known to many publishing in physics, engineering, or math (but few inther sciences).
* LaTeX is rendered very poorly in browsers which do not have built-in support for MathML, typically with coarse raster images, and font, size and aliasing mismatch.
* Inline with [Cover the common things people need|Goals] (is it?) - Yes!
* NotNew, a lot of wiki engines offer markup for superscript and subscript text. HTML offers it. But uses different markup.
===Disadvantages===
* Better alternatives exist
** Please elaborate which alternatives are available in which Wiki software
** Wiki engines supporting LaTeX includes: [[MoinMoin]], [[Oddmuse]], [[MediaWiki]], ... (add more)
** Wiki engines supporting image inclusion: practically all
** Wiki engines supporting simple ways to insert unicode characters/images (smileys): [[MoinMoin]], [[Oddmuse]], ... (add more)
** New markups to learn -- NotNew though.
* Users who already use the standard markups have to learn a yet another one.
* Markup characters can be hard to find on several keyboard layouts.
* The markup is hardly readable.
