You can multiply a number by a quantity, IIRC.  So you could write

    (display-space
      (* *dsssl-unit-length*
         (string->number (attribute-string attname (current-node)))

in your stylesheet.  Which brings us to the question:

I don't know.  But it shouldn't be hard to find out experimentally,
and then

(define *dsssl-unit-length* 0.001mm)

or whatever length you find.
