+Limitations of the provided locale formats
+==========================================

+Some locales use context-sensitive formats for numbers, which Djangos

+Switzerland (German)
+--------------------
+
+The Swiss number formatting depends on the type of number that is being
+formatted. For monetary values, a comma is used as the thousand separator and
+a decimal point for the decimal separator, for all other numbers, a comma is
+used as decimal separator and a space as thousand separator. The locale format
+provided by Django uses the generic separators, a comma for decimal and a space
+for thousand separators.
