typeOfStroage are defined as enumerations in SOL006. If tomorrow, we need to add another type of storage, e.g. 'lvm', the model would have to be revised and republished. This change proposes to make them identities which are much easier to extend, and do not need the entire model to be revised.
Proposed fix available in the merge request - WIP: Fix for bug#225.
Resolved after review and approval in SOL#95.
