# NOTE:
#
# * Omitted elements will be treated as empty (if string) or "false"
#   (if boolean).
# * Encoding is not relevant for XeTeX (which is utf8 always), and if
#   Document > Settings > Language > Encoding is not set to "Language
#   Default"
# * InternalEncoding is used to tell LyX that babel internally sets a font
#   encoding (such as hebrew to LHE). See bug #5091.
# * AsBabelOptions advices LyX to pass the languages locally to babel, not
#   globally to the class. Some languages (basically those not directly
#   supported by babel) need this.
#   FIXME: in this case, we might still need to pass the other languages
#          globally, for the use of other packages (such as varioref).
# * LangCode is also used for spellchecking and thesaurus, where the
#   dictionaries are named accordingly. Thus, check this when intoducing/
#   changing language codes (especially aspell, thesaurus).
#   TODO: maybe use Best Current Practice (BCP 47) codes for LangCode

#         http://www.w3.org/International/articles/language-tags/
#         http://www.iana.org/assignments/language-subtag-registry
# * LangVariety is used by the aspell spellchecker to differentiate
#   dictionaries for different varieties of a given language (e.g. German
#   pre-1998 and post-1998 spelling). The aspell dictionaries are named
#   language[_REGION][-variety].multi, e.g. de-alt.multi for "German (old
#   spelling)" (see http://aspell.net/man-html/Dictionary-Naming.html)
