Not exactly, from my poor English knowledge, I uderstand a leader is
made from dots ('.' chars). What I want here is white space, (or an
empty box).

.. But you need this font to see (or print) the document, no ?
As I understand your sentence, this is the same for TeX : Tex allows
to express the length of a text (or a box) but is unable to output a
dvi file if the fonts are not installed. *But* in TeX I'm able to take
my file and go to another machine where the fonts are. I thought the
same was possible with jade ? If not I miss something here and will
have to dig more deeply in the DSSSL document :-(

    Paul> So predicting the length of text in that font is impossible.

Thanks for your help
