Each Verify Failed Parameter or Overridden Parameter is used to specify a verification attribute that was either unverified (out of range), or overridden explicitly by the user. To uniquely identify both the context and value item of the attribute occurrence, a special notation is used, described in Section 10.17.
If a Verify Failed Parameter or Overridden Parameter refers to an attribute occurrence within a Control Point Sequence, then that attribute occurrence was failed or overridden during the administration of the beam segment immediately prior to the specified control point.
