Now just imagine Yukon with its http listener being able to produce XEN schemas and data streams, the first barrier between relational data and objects is gone.
Then (forgetting legacy XML for a moment) applications being able to easily produce, share and consume (at least within certain domain) XEN schemas and data streams as messages, the second barrier between objects and messages is gone.
UNIFICATION!
Don't you see how sweet it is?
Don't you see that there is something right now, spreading like a plague, that will make harder and harder to accomplish the elusive dream of unification?
And that 'something' is XML?
The best days of html are behind, it will be relegated as a text decorator (its initial purpose) and other more powerful formats will take its throne.
Believe it or not, the same will happen to XML. Sooner than later...
