I think this is not a general solution since it does not address other display aspect ratios, such as 21:9, which is becoming more common, and it is silent on every other aspect ratio.

Also, with the change to SHOULD, this allows unlimited characters/line on 4:3, which I don't think was intended.

An informative note should be added to state that the cellResolution needs to set accordingly since the initial TTML attribute value force 32x15 no matter what the display aspect ratio is.

This needs further discussion, think.

Here is a draft proposal for Issue-192 and Action-114 on R0041.

Change from: At most 32 characters must be present in any displayed text line.
Change to: No more than 32 characters SHOULD be present in any displayed text line where the aspect ratio of the root container is 4:3 and no more than 42 characters MUST be present for 16:9.
