CST - What info do we need to expose through API

[KFlash]

Kataw are using an CST. What kind of info from CST nodes do we need to expose through a public API.

Around 20 public API methods exist already.

Each keyword is it's own CST AST node with a flag that hold info if the keyword has been "escaped". A public method can be used to figure out if it's a keyword. Do we need to extend this? There are also public methods to check if the node is "escaped".
