My general thoughts about the first public draft of WCAG 3.0

I have to say that I'm quite pleased with the first draft. I'm not an
expert about WCAG 2.X but I'm quite familiarised with it so all the
announced changes generated so many doubts. Some of the doubts vanished
once I read all the draft and new questions appeared. Many of them will be
solved in future drafts (silver and gold levels).

I want to express my concern about the subjectiveness in the outcome
rating. Section 2.2.2 Outcome rating, second paragraph: "... the tester can
make an informed judgment about the outcome rating". I can understand that
to foresee all the possible situations and to generate objective tests and
instructions is not feasible but it is necessary to avoid any options to
introduce subjectiveness that potentially can bias the results.

I'm impressed with the change in the text contrast guideline. Finally, the
Contrast Sensitivity Function makes its way into the WCAG. As a
specialist on the human visual system, I'm really satisfied with this
improvement and I hope to see more inputs from vision sciences to web
accessibility.

Congratulations on all this hard work.
