Which level of Tuscany/SCA 1.x version should be used for the TravelSample in the sandbox?

[Raymond Feng]

Hi,

The TravelSample in the sandbox references 1.5 SNAPSHOT and 1.6 SNAPSHOT of 
Tuscany/SCA artifacts. Which version should be used consistently?

1) 1.5 SNAPSHOT
2) 1.5 release
3) 1.6 SNAPSHOT

Thanks,
Raymond
