I think there's a little confusion here about DSSSL.  DSSSL
stylesheets are SGML documents, but they usually use angle-brackets:

<style-sheet>
<style-specification>
<style-specification-body>

(default (make sequence))

</style-specification-body>
</style-specification>
</style-sheet>

The parentheses are only character data.

I don't think that Lisp could be made SGML compliant; the delimiters
could be redefined, but as Steve DeRose notes in _The SGML FAQ Book_,
there are some limits to the flexibility of the redefinitions, since
some delimiter roles are overloaded.  Also, Lisp doesn't have the
equivalent of start-tag close, and you can only omit tagc if the next
character is stago or etago (ISO 8879:1986, clause 7.4.1.2) which it
wouldn't be when you get to the leaves of a structure.
