This is description of the minion tag:
Minion is about how to use the Adobe Minion (Pro) font with LaTeX.
A complete set-up for text and maths fonts based on Minion Pro for (pdf)LaTeX is offered by the MinionPro project or FontPro (the latter supporting newer font versions and fixing some minor bugs). With XeLaTeX or LuaLaTeX, Minion Pro can be used with the help of the fontspec package.
and this of the times tag:
For questions specific to newtx, use the newtx tag. For question concerning the commercial MTPro2 math font, use mtpro. A good starting point is How do I make my document use the Times font, both for the text and the math?.
tags are regarded as good practice, I would propose other font specific
tags of frequent used fonts such as Garamond, Myriad, CharterBT, Helvetica. But I am not sure, if this really a good idea since there is myriad of possible font tags.
