List of differences between XML and JSON?

Hi Folks,

I am putting together a list of differences between XML and JSON. Below is the list that I currently have. Are there other differences, that I haven’t listed?

JSON is often compared to XML. However, there are significant differences:

-          XML supports comments, JSON does not.

-          XML supports processing instructions, JSON does not.

-          XML provides multiple syntaxes to express things (e.g., attribute values can be delimited by either a single or double quote, attributes can be in any order), JSON does not have such flexibility.

-          XML uses canonicalization to convert the XML into a standard form, JSON does not need canonicalization since multiple forms are not allowed.

-          XML has namespaces, JSON does not.

Any other differences?
