I have just recently written a stylesheet to turn a property-set into
a set of HTML pages, and into a modules dependency graph.  It is not
100% finished, but I already find the result incomparably clearer than
the plain SGML file :)

(Note: it has raised an issue about finding authoritative versions of
the propset DTD and of the SGML propset, which I have not resolved)

I'll have a dsssl-utils project created on savannah.gnu.org to host
this and other tools I and others may want to write.

I have also started to write a toy grove builder to get a better
understanding of all this.  The idea is to eventually turn it into a
toy dsssl implementation, and possibly into a production tool.

Yes, I confirm.  Trying to implement the thing raises interesting
questions, and possible future directions for the standards, who
knows...

Well, after writing several stylesheets using the limited DSSSL subset
provided by jade, I found the side-effect-free aspect of the language
*really* helpful, and I guess not many languages outside of functional
ones can express this adequately.

Indeed, each time I felt limited by the side-effect-free aspect, I
felt that the whole problem would probably have been simplified by a
preliminar transformation step.
