There are now people closing computer science questions as off-topic.
Could we stop that, please?
EDIT: The question has been reopened. I have cast my vote to close. If you think the question is off-topic...
While you raise a possibly valid concern, the example you choose is not right.
IMO, the MinML notation question is not on-topic on a Mathematics site.
I am thinking of it this way: Can a mathematics professor who has no knowledge of MinML answer this question without reading up about MinML? No.
The fact that this is the same notation used in Mathematics is irrelevant: you cannot possibly know that without understanding what MinML is about.
Given that MinML is not mainstream/a language which you expect a reasonable proportion of mathematicians to be familiar with(as you claim in a comment)/use, questions about MinML are very likely off-topic.
There are computer science questions which are on-topic and welcome here. That does not mean all of them are on-topic.
