One small nitpick.

This also needs its own @seealso entry.

Documentation/notation/input.itely:1340: Global settings can be kept in separate
files, which are selected
How about:
Global settings can be included from a separate file:

(global settings can also be kept in a separate file and included with \include,
so I'm not fond of that "... which are selected" bit.  Also, I don't think it's
necessary. and this change would give us 9 words instead of 15 words)

also, a final period.  It might also be good to wrap it into the previous
sentence, i.e. "... use of style sheets, as discussed in @rlearning{Style
sheets}.".
