Spec implementation

[MartijnR]

Not implemented yet:

• XForms actions (setvalue)
• ranking widget
• range widget
• local data encryption
• custom submission URL
• randomize() with translated options
• dynamic readonly (very low priority, very expensive)

Never to be implemented:

• turning off auto-submission
• turning off auto-delete

[MartijnR]

One way of doing this:

Focus on only on documented parts of spec and add tags like Microsoft Edge:

supported
in development
not currently planned
under consideration
preview

Add missing stuff to roadmap
