A pandoc lua filter that sorts definition lists
DefinitionList = function(dl)
local terms = {}
local inlines = {}
local blocks = {}
local sorted = {}
for i, item in ipairs(dl.content) do
local term = string.upper(pandoc.utils.stringify(item[1])) --string.upper() is used because all the terms were not capitalized in the example
table.insert(terms, term)
inlines[term] = item[1]
