6.1.2.1.2. Does it make sense to have all the node referencable to use
getNodeByUUID all the time?
Until it's applicable for a business logic it can be. But take
in account the paths are human readable and lets you think in
hierarchy. If it's important a location based approach is
preferable.
6.1.2.1.1. Is it better to use Session.getNodeByUUID or
Session.getItem?
6.1.2.1.3. What should I use to check if an Item exists before getting the
Value?
