Key names should be in constants (see extension_tts_api_constants for an example
of a contant-heavy API that was recently added).

[benjhayden, 2011/08/01 21:43:51]

Done.

You can use minLength in the schema file to enforce this.

[benjhayden, 2011/08/01 21:43:51]

Done.

[Mihai Parparita -not on Chrome, 2011/07/28 23:18:29]

Error names should be in constants. Also, is there a better error we can give
here? When would the resource dispatcher host be null? Should this just be a
CHECK?

[benjhayden, 2011/08/01 21:43:51]

Punted to a future CL that will use rdh_.

[Mihai Parparita -not on Chrome, 2011/07/28 23:18:29]

The pattern for optional keys is to use if (options->HasKey(kKeyName) {
EXTENSION_FUNCTION_VALIDATE(...)
