/* XXX see bug 1852:
 *
 * packet-gsm_map.c: There are 1174 display filter fields registered.  Most are
 * prefixed appropriately as "gsm_map", but many others are prefixed as
 * "gsm_old", or even "gad", "gsm_ss", or with no prefix at all.  I don't know
 * if the ones with "gsm_old" are simply obsolete display filter fields or if
 * they should be prefixed as "gsm_map.old." or what.  Similar uncertainties
 * for the others. Someone more knowledgeable than I am with respect to this
 * dissector should provide a patch for it.

 * This function is used to decode a message, when several encoding may be used.
 * For exemple, in the last MAP version, the Cancel Location is defined like this:
 * CancelLocationArg ::= [3] IMPLICIT SEQUENCE
 * But in the previous MAP version, it was a CHOICE between a SEQUENCE and an IMSI
 * As ASN1 encoders (or software) still uses the old encoding, this function allows
 * the decoding of both versions.
 * Moreover, some optimizations (or bad practice ?) in ASN1 encoder, removes the
 * SEQUENCE tag, when only one parameter is present in the SEQUENCE.
 * This explain why the function expects 3 parameters:
 * - a [3] SEQUENCE corresponding the recent ASN1 MAP encoding
 * - a SEQUENCE for old style
 * - and a single parameter, for old version or optimizations
 *
 * The analyze of the first ASN1 tag, indicate what kind of decoding should be used,
 * if the decoding function is provided (so not a NULL function)
