Some people seem to think downvoting is for everything you don't agree with. Well, I don't agree with that, lol! You are right, but HTML is a descendant of SGM

Some people seem to think downvoting is for everything you don't agree with. Well, I don't agree with that, lol! You are right, but HTML is a descendant of SGML which IBM invented specifically to make sure that data and formatting were represented separately. It was both a representation and presentation tool. Unfortunately, SGML hatched XML for data representation and HTML for presentation and never the twain shall meet. While Mimix will ship with an HTML-based user interface, the underlying structure of data in Mimix is not HMTL (or XML) but MSL, the Mimix Stream Language, a domain-specific language designed to describe writing. Owing to the open source nature of our product, we expect that the community will write new MSL engines with different interfaces and this is one of the most exciting aspects of the work.
