bold math not mathitalic

I am using the follwing (extracted) typescript lines for math in the  
lucida fonts:

\starttypescript [luc]
     \definetypeface [luc][mm][math][lucidayy][default] 
[encoding=texnansi]
     \definetypeface [luc][mm][bfmath][lucidayy][default] 
[encoding=texnansi]
\stoptypescript

\starttypescript [math] [lucidayy] [default]
     \definebodyfont [default] [mm]
       [mr=MathRoman mo 1, mi=MathItalic mo 1, ....]
\stoptypescript

\starttypescript [bfmath] [lucidayy] [default]
     \definebodyfont [default] [mm]
       [mrbf=MathRomanBold mo 1, mibf=MathItalicBold mo 1, ....]
\stoptypescript

\starttypescript [math] [lucidayy] [name]
   \definefontsynonym [MathRoman]         [LucidaBright]
   \definefontsynonym [MathItalic]        [LucidaNewMath-AltItalic]
\stoptypescript

\starttypescript [math] [lucidayy] [texnansi,ec,8r]
   \definefontsynonym [LucidaBright]                [hlhr8y]    
[encoding=texnansi]
   \definefontsynonym [LucidaNewMath-AltItalic]     [hlcrima]
\stoptypescript

\starttypescript [bfmath] [lucidayy] [name]
   \definefontsynonym [MathRomanBold]     [LucidaBright-Demi]
   \definefontsynonym [MathItalicBold]    [LucidaNewMath-AltDemiItalic]
\stoptypescript

\starttypescript [bfmath] [lucidayy] [texnansi,ec,8r]
   \definefontsynonym [LucidaBright-Demi]           [hlhb8y]    
[encoding=texnansi]
   \definefontsynonym [LucidaNewMath-AltDemiItalic] [hlcdima]
\stoptypescript

Typesetting:
\starttext
\usetypescript[luc][texnansi]\setupbodyfont[luc,10pt]\lucidatrue
{$\sqrt{a^2 + b^2} = c + \mf\sin{}x\quad {\ma NZRC}$}\crlf
\stoptext
  Gives me for the variables neatly LucidaNewMath-AltItalic.

But typesetting
\starttext
\usetypescript[luc][texnansi]\setupbodyfont[luc,10pt]\lucidatrue
{$\bfmath\sqrt{a^2 + b^2} = c + \mf\sin{}x\quad {\ma NZRC}$}\crlf
\stoptext
Gives me LucidaBright-Demi instead of LucidaNewMath-AltDemiItalic.
Everything else however (even the blackletters from ma) are in the  
correct bold math font.
The font must be present, because substituting MathItalicBold for  
MathItalic in the [math] script proves that.

It seems that mibf has not been substituted, but instead used the mr  
typeface.
Could this be a flaw in the (bold)math handling? For example a wrong  
fam chosen in the font switch?
It seems weird that everything behaves neat except for the bold math  
italic.

I am trying to define bold math myself, but encounter a problem with  
the typescripts.

Further probing into this matter (previous mail, see below) shows  
that the typescript delineated by ****'s is NOT USED AT ALL!
(Calling \setupformulas[method=bold] makes no difference).
It therefore does not seem a problem in the math family assignments  
in font-bfm.tex, as I first suspected.

Is there some special invocation needed for hooking up a user defined  
font set into $\bfmath ...$?
If have looked into font-bfm.tex  and font-ini.tex but could not  
figure it out.
Clearly I am misunderstanding the inner workings here, but I have no  
clue in which direction to look.

*** Changing the fonts in the above typescript does work ***

*** But not coming from my typescript I conclude from several  
experiments ***
