I'm suspicious over this statement. I can't see how libraries with a
minimum subsystem of 6.0 could ever have a chance of loading on an XP
box, unless the XP loader is insane enough to ignore such fundamental
restrictions. Part of the instructions [1] to implement v110_xp-like
targetting on the command line explicitly instructs to set the subsystem
to 5.01/5.02 and to use a specific flavor of WSDK 7.1.

If binaries built with v110 would work as-is, why bother with v110_xp's
distinct SDK and build settings?

I guess there might be enough luck involved by none of Boost using any
of the explodey parts of the WSDK, like ATL and the other mines, but it
still feels rather empirical.
