* Some languges, like Spanish, start exclamations and questions with an
up-side-down interpunctuation mark. So one could think of this as a
language dependent feature; one enters (logically) \Exclamation{Foo}, or
\Question{Bar}, and the language package inserts the correct

* In Swedish decimal numbers, the use of "," and "." are reversed relative
English, so a number that would appear as "123,456.78" in English, would be
"123.456,78" in Swedish. So, this could be considered as a language
dependednt feature; one enters (logically) \Number{..}, and the language
package selects the correct output format.
