Archived log file name. If set to NULL, either the log file was cleared before it was archived or an RMAN backup command with the "delete input" option was executed to back up archivelog all (RMAN> backup archivelog all delete input;).

using RMAN backup of archivelog all; with the "delete input" option will
remove "NAME" from V$ARCHIVED_LOG for those archivelog sequences in 10g.

In earlier releases like 9i we still kept the "NAME" of those archivelog
sequence# even if a rman backup of archive log all with "delete input" option
was used.
