Yes, under every version of DOS that I'm aware of, HIMEM.SYS is an XMS driver for 286 and above. Most people that have/had a 386+ just run EMM386 in addition to HIMEM, I'm assuming for the purpose of simulating EMS, especially because many DOS games required EMS specifically. I believe M$'s HIMEM.SYS driver simply provided an interface to the BIOS's XMS memory access functions which provided things like GDT's etc. but I don't know all the details.
I don't know if DOS6's HIMEM works on 286 machines. Someone told me DOS 7.10 (Win98) only runs on 386+ machines.
Anyway, glad we found a 286 user :)
DOS is intended for such machines indeed, but there's hardly any of these machines around in the wild.

I found out that FreeDOS's HIMEM.EXE is for 386+ only but i'm not sure why.
