No, sorry, I misspoke. I wouldn't say that it's *not* suitable (in 
fact, it has a very good glyph coverage in certain areas), just that 
using separate -- but similar -- fonts for text and math might end up 
being even better than just one.

In fact, I take it all back. STIX is fine for text, and so is TeX Gyre 
Termes. I guess I just meant to say that there are options available. 
But XTIS math, unless I am mistaken, should purely be used for maths.

If you want them in math, it should be possible to write

\setmathfont[range=\mathup/{num},Numbers=OldStyle]{XITS Math}

after the regular math font declaration, but I haven't tried it. I hope 
it works :)

If you ask me, I can add this as an option somewhere in the package. 
(I've seen old-style figures in maths in examples before, but never "in 
the wild".)
