I was traveling for most of the review period. I have a few comments to add to the extensive on-list discussions by other reviewers and the members of the UA working group. I have only skimmed many of these an apologize if I plow some of the ground again. My strong preference is simplicity, so I do not capitalize it.
Braille is a representation of text that depends on the language being represented.
It is certainly not a natural language. Braille is tactile, not haptic. My preference on politically correct language is to avoid offending people unnecessarily but to keep it simple. I personally prefer to be called a blind person than a person with blindness or a person who is visually challenged. The terms physical disability, visual disability, hearing disability, and cognitive disability are common well-understood relatively inoffensive terms.
