textcommand=\uppercase in setuphead is propagated to lower level settings

textcommand=\uppercase in setuphead is propagated to lower level settings

Hello.

I apply textcommand=\uppercase to a section heading but it is propagated to
subheadings.  Is there a good reason for this.

Some other notes in this test design:
1) textcommand=\uppercase does not work with luatex engine
2) textcommand=\WORD works in the luatex engine, but the propagation of
uppercase to subheadings is also encountered.
3) numbercolor=red only works with luatex.

I submit the pdf's also.

Thanks,
Dinh

Code:

%%% CHAPTER AND SECTION STYLING
\def\BookchapterCommand#1#2{\framed[frame=off,rightframe=on]{#1\space}\framed[frame=off]{\space#2}}
%\setuphead[chapter][command=\BookchapterCommand,page=chapter,numbercolor=red,alternative=inmargin]
\setuphead[chapter][command=\BookchapterCommand,numbercolor=red,alternative=inmargin]

\setuphead[section][numbercolor=red, after=\nowhitespace,
style={\ss\bfa},textcommand=\uppercase]
%% textcommand also applied on lower level headings.  Why?
%% Note: \WORD does not seem to work with textcommand for xetex and pdftex
engines, but \uppercase, \Words, \lowercase work.
%% For luatex, textcommand=\uppercase does not work.  Use \WORD.  But
encounter same problems of propagating the uppercase to lower levels.
%% also, numbercolor

\setuphead[subsection][number=no,style={\ss\bf},after=\nowhitespace]

\setuphead[subsubsection][style=slanted,number=no,before={\blank[big]},before={\testpage[1]},after=\nowhitespace]

\environment env_basic

all subsection inherit from their parent

sure, it's a low level tex command and never to be used in unpredictable 
situations (think of an \framed[frame=on]{...} being uppercased when you 
actually want ... to be)

also, it's unreliable for daily use which is why we have \WORD etc

indeed, inheritance

mkii (for pdftex/xetex) will not be patched so mkiv is the (future) 
reference in this
