We can adjust this, but it was never discussed in detail.
Can be done when we finalize the document.

This what discussed at great length.  
We determined that those instances that are big are expected to be so,
which would not be a problem.
Beyond that we cannot think of a number that makes sense, considering
the many potential values.

The goal was to make the test deterministic.  This test does that.

Please make a specific suggestion.  Which "info" are you referring to
specifically? There are many subsections.

The BP requires labelling and correct association.  Semantics cannot be
tested on a maschine basis in this case.

That is indeed listed as an open issue and I believe should remain so.
It prompts a tester to evaluate that point.
Do you have a specific suggestion to close this point?

This could be done, but addresses the BP document. 
This is under the responsibility of the group, not the task force.

Are you referring to the Sample Scope?  This links to test scope, which
in turn offers the grouping of resources from POWDER as a potential
As such the sample scope is completely open and does not refer to
anything particular.
Perhaps I misunderstand your point?

You left out an important word:  "conversely a title of "Uncle Tom's
Cabin" in an ebook page..."
This means that in such an example it would be expected.

Correct. Those are the expected colors for links.

> Shouldn't it be better something like:
> Excluding hyperlinks, does the page include any other text 
> with same color than hyperlinks? If yes, [FAIL]

Not necessarily, because the usage of different colors for links in the
first place is not very user friendly as it goes against convention and
thus makes the page less usable.
Especially on a mobile device with suboptimal lighting conditions and
potentially difficult to recognize colors in the first place, this
should not be a best practice.

I hope that clears things up.
Where I ask please do provide the appropriate information and, unless
somebody has problem with it, I am happy to fit it into the document
when I finish it.
