Ideally,
1. The default should be \mathupright (old behavior)
2. The user should have the option to change the font to \normalrm,
\normalss (or \normalrmbf and \normalssbf for titles).
In both cases, the style should not be affected by surrounding styles.

What I think I understand now is that it is impossible (it doesn’t make
sense) to concatenate elements (pardon my inaccuracy) inside one of
these elements.
indeed, in that case you need to set a mode after the first and act upon
that state
(btw, don't use sequential - stream based - flushing for everything,
sometimes it makes more sense to flush explicitly)

Re: [NTG-context] Changing font for math function
Hi Hans,
Thanks for the new feature in \setupmathematics.
I did some testing of the feature on a several documents, , and followed the
discussions you had with Aditya and Wolfgang.
Everything works fine, except that when one tries to modify, for instance the
definition of \liminf (in order to have it as an underlined lim), ConTeXt
reports an error.
Please see below the minimal example and the error message.
In the minimal example if you uncomment the lines modifying the definition of
\liminf on gets an error message.
begin test-functionstyle.tex
\setupmathematics
[functionstyle=\ss,
functioncolor=red]
%\unprotect
%\definemathcommand [liminf] [limop] {\underline\mfunctionlabeltext{lim}}
%\protect
\starttext
\startformula
f = \sin i\omega x^{\sin(x^{\sin(y)})}
\stopformula
Fatou's lemma implies
\startformula
\int_{\Omega}\liminf_{n\to\infty} (1+\cos(n|x|))dx \leq
\liminf_{n\to\infty}\int_{\Omega}(1+\cos(n|x|))dx.
\stopformula
\stoptext
end test-functionstyle.tex
The error message is:

I realize that this takes us back to the old 'bold-math-in-section-heads'
debate. With the current implementation:
\setuphead[section][style=bold]
\section{$\sin x$}
sin is bold, and if you implement the change that I am suggesting, then
\sin
will not be bold in section titles. If someone prefers \sin to be bolded in
section headers, he would have to add
\setupmathematics[functionstyle=\bf] in
the section style as well.
the next stage of the math font project will provide some real bold fonts (so
bold alphabets get heavy variants)

Hans,
many thanks for the explanation with \xmlsetup.
I have one more question for today concerning lpaths.

\xmlsetsetup{\xmldocument}
{span[@label]}
{xml:logo}
\xmlsetsetup{\xmldocument}
{span[contains(@class,'tex\letterpercent-logo')]}
{xml:tex:logo}
Is there no way to merge both in one? (The basic rule a|b doesn’t seem
