Re: [heycam/webidl] Extending an interface with boolean attribute with default value false (#880)

@TimothyGu 

> That being said, the API design looks pretty odd. In particular, forcing users to modify the `ssml` and `text` attributes separately could contribute to a temporary state of inconsistency between `ssml` and `text`, which IMO would be poor design. (E.g., `text` has been set to SSML text while `ssml` is still false.)

This is what we have. From the specification

> This may be either plain text or a complete, well-formed SSML document.

No language discloses how to disambiguate between the two potential inputs.


> In response to this, I'd propose making `ssml` settable through the constructor but immutable otherwise. In fact, if I were to design the API, I'd make all of these properties (`text`, `volume`, etc.) readonly; but if that's no longer possible, making `ssml` immutable and only settable through the constructor is the next best thing.

How does that look in "Web IDL" verbage?
