The official website at:
    http://www.gatekeeper.unicc.org/unece/trade/edifact


will start you with the usual EDIFACT documentation. I have not seen
anything which would suit a compiler-compiler. From my experience I
doubt that such a thing would exist. There are very few terminal
symbols in the EDI definitions; it is really just a compressible
record structure. The content is best defined by reference to one or
more lookup database(s). The record sequence and repetition count is
message type specific and the number of message types increases with
each version of the standard.
