When cross-references in the original paragraph and the translated
paragraph do not match, a warning is emitted. It is useful, because
it allows to catch mistakes, but it can also be an annoyance since
sometimes it is expected that the cross-references will not match.
For example, a reference that is repeated in the original text may
need to be factored out for good style in the target language.
Another example: if the translator needs to translate a universally
understood term in the source language into a term that not everyone
knows is the translation of this original term, adding a reference to
the glossary can be warranted. This allows the translated message to
start with '#noqa' in order to disable the warning.
