Fair point about the brackets as the use case is indeed different from the rest of TableGen. Let's find another solution.

However, if it's a single special character, do we need to implement a way to escape it? May be unlikely, but what if someone wants to use `$` in the description as a character? Longer string leaves less room for confusion. How about `%TEMPLATE%`?
