Bookmarking some a11y related references....

As I said, this is just a bookmark to something that, at some point, we will have to discuss...

In the PR on render methods #42 I saw this in the example:

    "outputPreference": {
      "mode": [
        "visual"
      ],
      "mediaType": "application/html",
      "style": {
        "width": "800px",
        "height": "800px"
      }
    }

it has not been discussed so far, but I am sure something like that will come up when we do a11y review (which must be done at some point). There is a reference that we may want to know about: Schema.org Accessibility Properties for Discoverability Vocabulary which would cover our need for the mode of the example. There are two properties in that vocabulary that might be relevant in a template: accessMode and accessModeSufficient. These properties are being used in digital publishing like EPUB but it strikes me as being usable for render methods as well...

(An aside: if the github discussion feature was switched on for this repo, this issue would fit there. Maybe it is worth using that tool...)
