[ResourceTiming] Clarifying a few things...

Hi All,

I'm looking at Resource Timing in a bit more detail again and have got
a few questions just to check my understanding is right...


1. Resource Timing doesn't mention the timings for the root HTML
document so I'm assuming they're not included and are just available
via Navigation Timing.


2. Should secureConnectionStart be included the list of attributes
(Section 4.5) that are set to zero when the Timing-Allow-Origin
response header isn't present?


3. clearResourceTimings discards the buffer entries up to the current
buffersize, and the buffer is re-populated starting with the resource
that's at buffersize +1 (if there are that many on the page)?


4. setResourceTimingBufferSize - trying get a clear understanding of
this sentence:

"If this method is not called, the default maximum number of
PerformanceResourceTiming resources stored must be 150, unless
otherwise specified by the user agent."

Is this saying "the buffer must be a minimum of 150, but a UA can
specify it to be larger", or does it leave open the possibility that a
UA can specify it to be smaller than 150?


Hopefully there are no daft questions in the list above...

Cheers

Andy
