Section 8 says:
It is better to include a unique identifier in the document when it is served and then pass that identifier as part of the URL in the src attribute of the eventsource element.
But there is no eventsource element or src attribute defined by this specification.
Section 4 says:
Resolve the URL specified in src, relative to the first script's base URL.
But the parameter to the constructor is named "url" not "src". Regards, Maciej
