Forgive my curiosity but I'm interested to know why.

It's pretty much a non-issue now: if the DTD is unknown or absent, then
you're not editing SGML, you're editing plain text.

brackets is enormously useful in dealing with the typical end-user's
imaginary markup systems, which traditionally require huge amounts
of character editing of the markup to make them validate.
