The way we (or at least I) imagined it, most decoders would be made to decode specific keys, i.e. that our generic DER decoder would be fairly unusual, because it tries to cover a multitude of ASN.1 structures in one go. So for more specific decoders that only care about a specific key type, we imagined that the ASN.1 structure would be defined by the provider in question for whatever they need, and a d2i function would be used to try to decode the blob... or if the provider authors prefers, a completely different DER decoder could also be used. After all, we've tried very hard not to lock providers to depend on OpenSSL libraries for that sort of thing.
