Re: CfC: Issue 157

when the text said it was a comment on a last call — what was it a last call on? 

if the quote was from a last call on WCAG - before it was issued - then the quote was from 2008 (even if quoted in a 2014 email) 

was it a last call on WCAG?  or a last call on some document being released in 2014?

The WG specifically discussed this and decided that it did NOT (and should not need to meet it in all states.  There was a long discussion and debate about it at the time — but the consensus was that it should not meet in all states (as noted below).   So it may not have been put into the Understanding WCAG 2.0 (which it should have) but it is documented what the working group meant when it went to final consensus vote.     So that is the meaning of the SC that was passed by the WG.

>> ​Absent here is the notion of "state" - the SC neither explicitly includes or precludes the idea that "text", and the color of the text, can change dependant on state (visited, unvisited, active, onHover/onMouseover, etc.). Whether this was by conscious design, or an error of omission I do not know, but a strict reading of the SC clearly does not explicitly address that concern.

>> 
>> HOWEVER I also note that this opinion was never incorporated into the Normative Requirements​ (and that finding the opinion/decision would likely be onerous to those not familiar with the ins-and-outs of W3C archiving :) ) Further, there is no mention of this opinion/decision in the Understanding documentation for either SC1.4.3 nor SC1.4.6
>>

>> I would suggest that the best way forward would be to ensure that the decision (as well as the prior decision) be captured in the Understanding documentation, with a note that content created prior to the opinion not be held accountable to the opinion in terms of success or failure - yes, that feels squishy, but I cannot think of another way out: officially the SC says nothing.
