Protected mode interfaces are really your only choice to do this
transparently.

The problem is that XMS memory isn't in the 8086's addressing space,
so you can't access it directly in real mode, only through handles and 
XMS service requests.  It is in theory possible to write a compiler
that could hide all this for you, and I believe MAC compilers do
something like this, but I can't see anyone doing it for MS-DOS and
XMS because of the huge overhead involved.
