Objects of this kind conveniently represent locales usually described by
locale identifiers such as de_DE, en_Latin_US etc. The locale identifiers
used are defined in the Unicode Technical Standard #35 (Unicode Locale
Data Markup Language).
Using this class asserts the validity of the used locale and provides you
with some useful methods for getting more information about it.
Please note that this class represents locale identifier with valid syntax,
but it does not assures that represented locale is available (installed) in
current Flow installation. In order to check that, various methods of
\Neos\Flow\I18n\Service class can be used.
