add a collation to use in grouping+sorting by languages
output descriptions in language group order
force font size of footnote numbers to always be the same regardless of the font size of the parent container; force arial and sans-serif on english-language content; capitalize the first letter of each list item inside the description div
make sure we actually subsort this list of descriptions on content so that within language groups, multiple descriptions of the same language (should we ever have them) are emitted in language-specific alphabetical order
