-# * 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). This prevents LyX from outputting
-# characters that only exist in T1 font encoding (such as "<", ">", "|"
-# and straight quote). See bug #5091.
+# * DateFormats lists the localized conventions for three date forms:
+# - Long: December 1, 2018
+# - Medium: Dec 1, 2018
+# - Short: 1/12/2018
+# These are separated by | and use the QDate syntax:
+# * d the day as number without a leading zero (1 to 31)
+# * dd the day as number with a leading zero (01 to 31)
+# * ddd the abbreviated localized day name (e.g. 'Mon' to 'Sun')
+# * dddd the long localized day name (e.g. 'Monday' to 'Sunday')
+# * M the month as number without a leading zero (1 to 12)
+# * MM the month as number with a leading zero (01 to 12)
+# * MMM the abbreviated localized month name (e.g. 'Jan' to 'Dec')
+# * MMMM the long localized month name (e.g. 'January' to 'December')
+# * yy the year as two digit number (00 to 99)
+# * yyyy the year as four digit number
+# * Encoding is the default encoding used with TeX fonts.
+# It is only used if Document > Settings > Language > Encoding
+# is set to "Language Default" and "use non-TeX fonts" is FALSE.
+# Encoding "inherit" means: keep encoding of the context (used by
+# latex_language).
+# * FontEncoding is a bar-separated list of font encodings.
+# The first value is the required font encoding for correct hyphenation with
+# 8-bit TeX (http://www.hyphenation.org). Eventually following values may be
+# used if the selected font is unavailable in FontEncoding. They provide all
+# letters used in the language, but some only as "surrogate pairs" with
+# possible problems for hyphenation and drag-and-drop from the generated
+# documents.
+# If not given, all standard text encodings (T<n>) as well as OT1 work.
