TD Issue 901

   <kaz> [19]TD Issue 901

     [19] https://github.com/w3c/wot-thing-description/issues/901

   Issue #901 in WoT Thing Description repo about multiple
   security schemes reviewed (esp. with respect OR/AND)

   1. Array of arrays: [["sc1","sc2"],"sc3"]. Problem: nesting
   depth changes AND to OR; special rule that array of one element
   can be treated as a string may not work
   2. Wrapper object: { "and": ["sc1", "sc2"], "or": "sc3"}.
   Breaks compatibility.
   3. Farshid's suggestion above: {"scheme1": { "scheme2": {}}}.
   This is like a LISP CADR list... breaks compatibility.
   4. Another option would be to define "or" (and maybe "and" for
   completeness) schemes in "securityDefinitions"

   Proposed next step: create PR for option 4, this PR should be
   incorporated in TD 1.1

   Additional consideration: can be array-of-flows be made

   Other additional consideration: more compact notion for AND/OR

   The alternative notations come with challenges with respect to
   backward compatibility and parsing complexity. Closer
   examinations are needed

   Michael to care about creating the above mentioned PR
