[whatwg] Encrypted HTTP and related security concerns - make mixed content warnings accessible from JS?

[Ingo Chao]

For automated error reporting, say for a HTTPS mashup page with 3rd
party advertisement content, I would like to have a security warning
thrown for the mixed content situation (HTTPS mixed with HTTP
content), accessible from JavaScript.

Would that be possible to specify?

Thanks
 Ingo
