Note that I have said *parser*. The syntax of DSSSL is far simpler
(and far more uniform!) than CSS.
I agree that the implementation of a full DSSSL engine would be much
larger than a CSS engine, but I don't think DSSSL-O would require all
that much extra work/code.

STTP is not required for DSSSL-O.
