A question that is off topic is one that has been voted off topic. The faq is really just a loose guideline. A question is determined to be off topic if a sufficient number of members with a minimum amount of reputation vote it to be off topic. According to the privaleges page on the matter:
Closing is a democratic voting process where the community defines
- what questions are generally on-topic and generally off-topic for this site.
- what questions are duplicates.
Thus, by definition, a question is off topic if it has been voted to be so.
On to the question in question! From what I wrote in the comments:
In my opinion this question falls outside the guidelines given in the
faq. Involving Word is not the issue, as raxacoricofallapatorius
pointed out such a question
earlier (with not a single downvote).
Rather, this question involves software emulating the output of LaTeX,
and historically such questions have often been determined to be off
topic. Mathjax is another common candidate for closures for this
reason.
The issue of what is off topic is hazy around the boundary...
Nonetheless, I think this question is off topic, since there is no TeX
processor involved and the "LaTeX" code here is a subset.
I'd like to add that this is not a criticism of Word, MathType or MathJax,
which I mentioned earlier (I make extensive use of MathJax in fact). We
simply have to draw boundaries.
