Rose was talking about a feature of ASN.1 (MACROs) that was removed and replaced with the Information Object System (x.681, x.682, x.683).
I'm not that familiar with the ASN.1 MACRO facility, no, because, after all, it's gone and replaced. My understanding is that the problems Rose identified led to the MACRO system being replaced -- good!
So yeah, I don't really know what Rose was talking about, but I do know plenty about the x.681/682/683 specs since I've implemented a subset of them.
