I suspect that the diversity of schema languages is going to be one of
the issues people will face in 2027. People will have to be able to
understand XML governed by a mix of DTDs, W3C XML Schema (in different
versions?), Relax-NG, and several other schema languages that haven't
yet been invented.
Of course, in many cases they may just ignore the schemas, or use the
schemas just as reading material to help them understand the basic
structure. And if we're lucky, there will be tools to convert all the
major legacy schemas into TOTSL (The One True Schema Language).
