Since some style attributes are permitted in Image profile, permit #initial

[nigelmegitt]

There are style attributes that are permitted in Image Profile, such as tts:backgroundColor, tts:display, tts:luminanceGain etc. so it makes sense to permit #initial in Image Profile for ease of styling, and symmetry with Text Profile.

[palemieux]

I am not aware of Image profile use cases that cannot be fulfilled without initial, and not aware of Image profile users that have requested that feature.

[nigelmegitt]

OK but it's weirdly inconsistent. If we think initial is useful for Text Profile, why would it not be useful for Image Profile?

The Working Group just discussed Since some style attributes are permitted in Image profile, permit `#initial` imsc-vnext-reqs#36, and agreed to the following:

• SUMMARY: No immediate requirement to `#initial` has been identified, closing with no action until such a requirement is raised.

<nigel> github: https://github.com//issues/36
<nigel> Nigel: I think we're out of time to do anything about this in IMSC 1.1. We didn't action
<nigel> .. this in the CR2 transition request.
<nigel> Pierre: No, and the idea really is to modify the Image profile as little as possible, if at all.
<nigel> .. I've not heard folk being unsatisfied with Image Profile. Users of the Text Profile were
<nigel> .. quite vocal with strong opinions, but I've not seen any documented feedback on the
<nigel> .. Image Profile so my philosophy is not to modify it without anyone expressing that opinion.
<atai2> +1
<nigel> .. Same applies to position.
<nigel> Glenn: Did you add the new image element?
<nigel> Pierre: Yes, and deprecated smpte:backgroundImage.
<nigel> Nigel: I take your point, though it does seem inconsistent.
<nigel> Glenn: How about tts:showBackground? Everyone seems to want to change that.
<nigel> Pierre: If you're using an image you'd typically use a transparent background.
<nigel> .. Basically I've seen a lot of full raster images for Image Profile.
<nigel> .. What we can do about this is either close it as "won't do" (for now), or just leave it
<nigel> .. open and mark for v.next. I think I'd rather just close it.
<nigel> Pierre: Here the question is if someone cares. If nobody cares we should close it. I don't care!
<nigel> Nigel: I don't have any plan to use Image Profile for anything, so it makes no difference to
<nigel> .. me in usage.
<nigel> Pierre: My suggestion would be to close it.
<nigel> SUMMARY: No immediate requirement to `#initial` has been identified, closing with no action until such a requirement is raised.
