For the "pattern" example, is the general idea to communicate the characters allowed in the name? ie VMware (for example) may allow just the chars above, but not things like "-", "_", "+", ";", etc. Whereas some other Cloud Provider might. Could be useful when importing existing images from a given cloud provider. Especially if they're to then be pushed to another one.
