Generally, Docutils follows the "best current praxis" `BCP 47`__ which
says that any specifiers (like the region subtag here) is optional.

Czech-language mappings for language-dependent features of Docutils.
are in the files

  .../docutils/languages/cs.py
  .../docutils/parsers/rst/languages/cs.py

that are used for any of the above language tags.

In some cases, special files for sub-locales exist, e.g., "pt_br.py" for
Brasilanean Portugese.


The HTML writers also insert the original language tag into the document
header.

The XML writer uses the language tag to support "localized" directive names.
It does, however, not insert a language tag into the output document.
This is IMO a bug.

The LaTeX writer translates the tag into a Babel language name
(or with XeTeX/LuaTeX a Polyglossia name), if there language is supported.
Subvarieties (de-1901, de-CH, de-AT, say) are respected, if supported by
Babel/Polyglossia, e.g.

        'en-AU':        'australian',
        'en-CA':        'canadian',
        'en-GB':        'british',
        'en-NZ':        'newzealand',
        'en-US':        'american',

This seems wrong in any case. It should stay "cs" without the optional
region subtag.

There is a function to iterate over "normalized" language tags:

  utils.normalize_language_tag()
  
    """Return a list of normalized combinations for a `BCP 47` language tag.

    Example:

    >>> normalize_language_tag('de_AT-1901')
    ['de-at-1901', 'de-at', 'de-1901', 'de']
    """
used, e.g., in the latex writer, the smartquotes transform and
``parsers.rst.languages.get_language(language_code)``.

Maybe this can also help in the odt writer?
