/** Identifiers for on-ledger objects.
Each ledger object requires a unique type identifier, which is stored within the object itself;
this makes it possible to iterate the entire ledger and determine each object's type and verify
that the object you retrieved from a given hash matches the expected type.
@warning Since these values are stored inside objects stored on the ledger they are part of the
protocol.
**Changing them should be avoided because without special handling, this will result in a hard
fork.**
@note Values outside this range may be used internally by the code for various purposes, but
attempting to use such values to identify on-ledger objects will result in an invariant failure.
@note When retiring types, the specific values should not be removed but should be marked as
[[deprecated]]. This is to avoid accidental reuse of identifiers.
@todo The C++ language does not enable checking for duplicate values here.
If it becomes possible then we should do this.
