suggested bindings for actions must include subpaths (e.g. ".../input/trigger", which the runtime binds to ".../input/trigger/value" for a BOOLEAN)

[bradgrantham-lunarg]

For all fully-specified paths, e.g. /user/hand/left/input/trigger/value, the API layer must also add the parent path, e.g. /user/hand/left/input/trigger/, to WellKnownStrings because an app can specify, e.g. BOOLEAN action binding to /user/hand/left/input/trigger/ and runtimes must take that path for BOOLEAN to be /user/hand/left/input/trigger/value.

This may prevent UE4 from working since those paths come through an app running in UE4 in current testing.
