AllowCrossTargeting in .fsproj files

f#

Solution

If you search the F# 3.0 sources for `AllowCrossTargeting`, it only appears in one place: `fsharp/src/fsharp/Salsa/salsa.fs, line 686`.

Since it appears to be a write-only property as far as F# is concerned, my guess is that it has something to do with allowing the F# compiler to run on one version of the .NET framework whilst targeting another version. Other than that, searching Google for the property name only turns up `.fsproj` files -- so it doesn't appear `AllowCrossTargeting` does anything at all right now.

Problem

What's the effect of having ``` <AllowCrossTargeting>true</AllowCrossTargeting> ``` in a fsproj file? I can't find any documentation about it
