The XML things is quite amusing, given how far out of favour XML went. XML has now failed hard AFAICT.
But I can agree the spirit of the prediction lives on in the form NoSQL and JSON.

There are cases where XML is a great format. For example in the past I wrote a system for interfacing with a government department.
The thing was an epic of about 30 different schemas, however being able to actually look at a concrete schema for specification and actually be able to test against it was invaluable.
Trying to build that thing with JSON would have driven me to tears.
I too like the ability to validate XML against a schema and found it invaluable when dealing with a set of (needlessly) complex ant-plugins a couple of years back.
XML, JSON, MUMPS are semantically equivalent.
But in fact: you add javascript - you have all strictness and structure of XML.
