I think there's a little confusion here about DSSSL. DSSSL
stylesheets are SGML documents, but they usually use angle-brackets:
(default (make sequence))
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 188.8.131.52) which it
wouldn't be when you get to the leaves of a structure.
