MS Word illegal?
Hmmmm ... so essentially they patented the use of SGML (and thus XML) as an integral part of a document editing package. I'm not sure that there's programs doing that prior to the 1994 patent. If one can be found it would invalidate the patent, I think.
The patent is actually a bit more generic, covering any method of keeping text and formatting separate in a documenting editing program. Given the prior existence of SGML for nearly 20 years, even if no one had done this before I'm not really sure it counts as "non-obvious".
