It is an "XT clone" in the sense that the term was used back in the 1980s. In that era, there were a whole bunch of "IBM PC clones" "IBM XT clones" "IBM AT clones", all different in some ways than the original IBM brand computers from which they "cloned", but, at least in theory, all providing compatibility with at least all the features of their namesakes, and usually some additional features or performance improvements as well. Including XT clones with V20, V30, and 80186 processors. So in this "traditional" sense, this is indeed an "XT clone", in that it will run all the software that would run on an XT, plus it has many additional features as well. Likewise, I can't call it an "AT clone", because it can't run all the software that an AT could run.
