Elliotte Rusty Harold on the bad idea that’s Efficient XML:

They’re some nice graphs and tables that make EXI sounds like a good idea when taken at face value, but some of the claims the documents makes for XML are simply false; and some of the goals it sets for EXI are actively harmful (specifically the ones that involve schema awareness.) I’m getting a little verklempt. Talk amongst yourselves. I’ll give you a topic: a Efficient XML Interchange is neither efficient, XML, nor interchangeable. Discuss!
