WARNING When a version is in archival status, it is considered frozen,
protecting its data from modification. However, archival status
does not freeze the dictionary structure. Therefore, if the
dictionary structure is changed, the structure of archival
versions is also changed. In the case of additions to the
dictionary structure, no serious problems will result. However,
deletions from the dictionary structure may be detrimental to
archival versions. Therefore, this should be considered when
making deletions that affect dictionary structure.
