Specification 2.2.0

The *scenario selector* below can be used to narrow down the required fields
for a selected authentication scenario. Please note the following:

1. When ``All`` is selected in both dropdowns, no type filters are applied.
   I.e. both ``sdkTransID`` and ``browserUserAgent`` is marked as required,
   even though they will never appear in the same message.
2. When a Message Category or a Device Channel is selected, messages will be
   filtered if they are not relevant for the selection. The inclusion might
   change from e.g. required to optional
