Description Silvia Pfeiffer 2015-02-22 10:25:40 UTC
The snap-to-lines flag is of type Boolean that can be "set" to 
"true" or "false". Instead of referring to these values sometimes the 
setting of the values is described with the verbs "set" (for setting to 
"true") and "unset" (for setting to "false"). It would be more 
consistent and help the reader if the operation is always described as 
"set to true" and "set to false".

As per feedback from Andreas Tai:

I can only find one such instance, in

"On setting, the text track cue snap-to-lines flag must be set if the new value is true, and must be unset otherwise."

I guess this could be simply be "On setting, the text track cue snap-to-lines flag must be set to the new value."

But I would value consistency with so would prefer no change.

I found an unrelated problem though:

Actually, there is a difference in what the browser stores internally during processing (parsing, rendering, API) to what the concept's value is. The concept's value is more closely related to what an author would set in a HTML attribute. Since a boolean attribute is "set to true" with any value, it's only false when unset.

I think we need to leave this as is.

I cannot find any places where we describe snap-to-lines as merely 'set'; it's always true or false now.

The terminology was changed in So although this issue is not referenced in the commit message it resolved the issue by following the proposal.
