It's too powerful to fit JSON.  In particular, in E4X you can incorporate
arbitrary JavaScript expressions within braces into character content and
attribute values.  JSON is not about arbitrary JavaScript expressions.

Not just in browsers, but everywhere else too.  XML's data model is inherently
much more complicated than anybody needs.  By streamlining the data model
to elements with a name, an attribute map, and a child sequence you get
way past the 80/20 point with much greater ease of use.
