This thing is designed for representing common data structures (array, set, date) in JSON. XML does not have that too. It's not validator such as XML Schema (JSON has JSON schema which is quite popular), it does not check anything.

If it's not a validator, then what's the value? Why would I use this?

I assume the TJSON libraries throw errors if invalid types or formats are provided --- which is good, but that makes this a validator. Developers have been representing non-standard formats in JSON for years.

Google's response to JSON's limitations was the Protocol Buffer [1], and as I understand it, it's used internally relatively extensively, but there hasn't been much adoption outside of Google. JSON is just the right mix of simple + robust for the majority of use cases.

XML provisions an extensible way to markup your data though - TJSON is just a hack upon JSON...and it's full of potential problems that XML has solved years ago.
