  Sample input:
ISO8601ParseDate("1975-06-09")
  Sample output:
06/09/1975

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Tries to be strict in parsing, to avoid any invalid characters, decimal points, and out-of-range issues with months / days.

Did you know that YYYY+MM+DD is a valid `DATE` field for FileMaker? You can just Substitute( theDate ; "-" ; "+" )
This should work to return m/d/yyyy (or d/m/yyyy for those who use it). Make sure the result is DATE type. IDK FM the version that this became possible, so YMMV (or YKMV).
