typescripts

I've seen examples like this:
\definefontfeature
 [fea]
 [mode=node,language=dflt,script=arab,
  init=yes,medi=yes,fina=yes,isol=yes,
  liga=yes,dlig=yes,rlig=yes,tlig=yes,
  calt=yes,trep=yes,mark=yes,mkmk=yes,
  kern=yes,curs=yes]
so I think you mean to say that I can apply only one feature to
\definefontsynonym or to \definetypeface.  I tried this and it
checks out.  Thanks---it's nice to see hz working.  Protrusion is
only on the right margin?

You need more typefaces. One for light, another one for condensed etc.

Thank you both.  I want to begin experimenting with this, but there's
one thing that still confuses me.  If I have a font with say, forty different
combinations of weight/width/shape (5x4x2), I will need to come up with
forty different pairs like:
myNewFontSwitch=SerifMyFontVariantName sa 1,
a strain on the poetic imagination, but possible.
It would be nicer though, if I could change weight/width/shape independently
of each other (then I need have only 5+4+2 switches).  For example, when
I see something like:
\rm\tf roman \it italic \bf bold
resulting in:
<book roman> <book italic> <bold roman>,
it's surprising to see that \bf has turned off the italic---you don't
expect a switch
of the weight to have a hidden switch of the shape in it.  Could the typescript
be set up with fewer switches, so that:
\rm\tf roman \it italic \bf bold
would result in:
<book roman> <book italic> <bold italic>,
or, e.g.,
\rm\tf (regular book roman) \cd (condensed) \it (italic) \bf (bold)
would result in:
<regular book roman> <condensed book roman> <condensed book italic>
<condensed bold italic>?



(Also, I'm hoping that having a dozen different sets of font features won't
require twelve times as many switches and feature names as this.  I think
there is some easier method for switching---Hans mentioned \addff{}, but
I can't find anything in the docs.  If that works, that would make two kinds
of switches, one for some kinds of features and another for other kinds.)
