The raw file content as a Lua string. You can examine the
arguments you get like so:
·······································································
\startluacode
document.arg_test = function (s, ...)
table.print({...}, "file_content")
return s
end
local textfileactions = resolvers.openers.helpers.textfileactions
utilities.sequencers.appendaction(textfileactions,"system","document.arg_test")
\stopluacode
\starttext
\input ward
\input knuth
\stoptext

Split the input at every byte and re-concatenate using "+" as
delimiter. (It’s a bit confusing as string.totable() takes only
one argument ;-) )

The sequencers use loadstring() internally (util-seq.lua), so you
need to supply the namespace as a string. This happens all over
the place with action/callbacks.
