Of course this looks most sane. But I'm asking if you're going to make
use of the dwEmulatedVersion other than "< 0x200"? That is, under what
circumstances we should emulate version 2 or 3 when we have support
for version 5? It's interesting to me, because it seemed to me that
the native versions (starting with 2.0) are very compatible to each
other.
