Hi all, I'm looking for a tool which can automatically generate from an ASN1 type-definition a constraint-definition. If CHOICE is present in the type-definition it should generate a constraint for all sub-elements of the CHOICE (recursively). Does anyone know such a tool (or similar, which can help me for this purpose a bit) ? Many thx in advance Endre > ========================================== > Endre Szalai > Software Developer > Conformance Center > ERICSSON Hungary > > tel> +36 1 437 7796 > fax> +36 1 437 7767 > mail> [EMAIL PROTECTED] > ==========================================
