Some questions to ask when developing interactive content
  -  Can the technologies relied upon  meet WCAG 2.0?   (Choosing baseline technologies)
 
  - If a user isn't able to use the technologies required to view the content, what will their experience be? 
 
  -  If an aspect of content (or interactivity) is modality-specific, is there an alternative available?  (Guideline 4.2)
 
  - Are XML schemas, APIs, or other customizable frameworks designed to support accessibility?
 
  - Do the interactive aspects of  interactive content interfere with accessibility? 
 
  - If users can submit or otherwise modify content, do the authoring tools provided within the content make it possible to meet WCAG? (ATAG) 
 
  - Are there global preferences that could be set to enhance accessibility? (SCR14)
