Wrong! \markup can be used more or less everywhere where you can use
a text string, in order to get more freedom to change fonts, or typeset
more or less whatever you want. For example, you can use
\mark \markup{ \large "DS. al Fine" }

So, two completely different concepts are involved here:

- Text scripts versus rehearsal marks: A text script is typeset using
  c4-"string" or c4-\markup{...} and is placed above the specified note.
  "Rehearsal marks" on the other hand are typeset using \mark "string"
  or \mark \markup{...}. If you specify the \mark command at a bar
  line, the resulting mark is placed above the bar line, if you specify
  it in the middle of a bar, the resulting mark is positioned between
  notes. Finally, if it's specified before the first note if a score
  (or in general at the beginning of a score line), then it's placed
  before the first note of the line.

  To summarize, use text scripts to place things above a note,
  use \mark to place things between notes, above bar lines or before
  the first note of a score line.
  Another main difference is that \mark is only typeset above the
  top stave of the score, whereas text scripts are typeset for each
  stave. So, this makes \mark useful for rehearsal marks, tempo
  indications, fermatas, Da capo, segnos, Fine and so on.
  A tricky detail about \mark is that if it appears at a line break,
  then it's typeset at the beginning of the next line instead of over
  the last bar line of the previous line unless you fiddle with the
  break-visibility. Of course, the default makes perfect sense as long
  as you use \mark for rehearsal marks.

- Simple text strings typeset using the default font versus text
  markups, i.e. "string" versus \markup{\italic \large string }.
