[imsc] APA WG comment: Author proposes, user disposes (#523)

michael-n-cooper has just created a new issue for https://github.com/w3c/imsc:

== APA WG comment: Author proposes, user disposes ==
There is a general issue with the way that an author specifies layout characteristics of captions and subtitles, such as font size, font family, line height, background and positioning.  It should be made clear that authors can and should define the viewport and text characteristics, but these definitions may be overridden by the user by setting up their user agent to better meet their particular needs as users (cf. [MAUR, 3.7 Requirements on the use of the viewport](https://www.w3.org/TR/2015/NOTE-media-accessibility-reqs-20151203/#requirements-on-the-use-of-the-viewport)). For example, a user with vision impairment who also requires caption support may want to have all captions displayed in the lower third of the screen with a large font, disregarding the definition of various viewports and font types defined by the author.  We recommend adding a note to the spec to advise authors that  the final rendition of their document may not follow their specified styling and positioning, but follow user-defined styling and positioning instead.
