Not as far as I'm concerned. Most HTML product vendors don't take the SGML
standard seriously, probably because most web info providers are not much
concerned with document interchange, structure driven search, etc.

An application of James Clark's sp parser, and a successor to "sgmls". It's
freely available at places like the SGML archives at ftp://ftp.ifi.uio.no.
I use nsgmls to validate HTML as SGML and translate the parser output into
"browser HTML".
