NAACCR XML: Tumor.overRideTnmStage

Description
Some computer edits identify errors. Others indicate possible errors that require manual review for resolution. To eliminate the need to review the same cases repeatedly, over-ride flags have been developed to indicate that data in a record (or records) have been reviewed and, while unusual, are correct.

This over-ride is used with the following edits in the NAACCR Metafile of the EDITS software:
These edits check T, N, and M combinations against stage group. Adding this over-ride allows the edit to pass when combinations of T, N, and M are entered that are not included in the stage tables used with the edits. 
 
Rationale
This over-ride will allow registrars to enter combination of T, N, and M with a stage group that differs from the combinations documented in the AJCC Staging Manual.
