Dear list,

I have been using the Lucida fonts for long time with LaTeX, either the
Type 1 version through the `lucimatx` package or the OpenType variants

to select stylistic sets, e.g. alternative calligraphic glyphs.

By default the `lucidaot` typescript switches off the alternative math
italics, but I found a way to reenable them (basically just undoing what
the typescript does).


\setupbodyfont[lucidaot]
% get alternative math italics
\setupmathrendering[lucidaot][it=]
\starttext
$\mathcal{C} = f(x)$
\stoptext


I only found this by chance; \setupmathrendering is not documented.  Is
there a more intuitive way to select the alternative math italics?
Also, is there an easy way to access all the other features defined in
`lucida-opentype-math.lfg`?  This is the list:


alternates = {
italic   = { feature = 'ss01', value = 1, comment = "Mathematical 
Alternative Lowercase Italic" },
arrow= { feature = 'ss02', value = 1, comment = "Mathematical 
Alternative Smaller Arrows" },
operator = { feature = 'ss03', value = 1, comment = "Mathematical 
Alternative Smaller Operators" },
calligraphic = { feature = 'ss04', value = 1, comment = "Mathematical 
Alternative Calligraphic Characters" },
zero = { feature = 'ss05', value = 1, comment = "Mathematical 
Alternative Zero" },
partial  = { feature = 'ss20', value = 1, comment = "Mathematical 
Alternative Upright Partial Differential" },
},


I extended the mechanism a bit so in the next beta you can do 
combinations and a global setup:


\setupbodyfont[lucidaot]

\starttext

$x
   ^{i \leftarrow 0 = ∅}
   _{\setmathfontalternate{arrow}
 \setmathfontalternate{dotless}
 \setmathfontalternate{zero}
 i \leftarrow 0 = ∅}
$

$x
   ^{i \leftarrow 0 = ∅}
   _{\setmathfontalternate{arrow,dotless,zero}
 i \leftarrow 0 = ∅}
$

\setupmathematics[stylealternative={arrow,dotless,zero}]

$x
   ^{i \leftarrow 0 = ∅}
   _{i \leftarrow 0 = ∅}
$

\stoptext

I have two follow-up questions.  First, is there a similar thing for
paragraphs (à la mixedparagraphs)?  Second, why are there two distinct
mechanisms for columns?
