Yes, I'm talking to you. You're right, you didn't say anything about syntax and semantics. I did. Go back to the beginning of the thread:

Note the use of the word syntax. I'm talking about syntax. All of your responses have been at best irrelevant or at worst wrong because you either don't understand what syntax is, or you chose to ignore it. It's damned annoying, particularly when you start making demonstrably false claims like, "it's nowhere close to the power of SGML as a text format" (https://news.ycombinator.com/item?id=13569991).
