Hi all,

While testing some XITS symbols, I was wondering about the spacing of
the following symbols:

\setupbodyfont[xits]

\starttext
$$a < b$$ # reference
$$a ⨼ b$$
$$a ⨽ b$$
$$a ⪝ b$$
$$a ⪞ b$$
$$a ⪬ b$$
$$a ⪭ b$$
\stoptext

Not sure about the first two, but I think the rest should be mathrel
(additionally, does anyone knows a definite Unicode reference for such
proprieties?)

Regards,
 Khaled
