LARTC - May 2004 - reclassify option on policing

Hello,
What exactly is the use of the "reclassify" option in the policing
options of tc filters?
According to LARTC: 
 
"
reclassify 
Most often comes down to reclassification to Best Effort. This is the
default action.
"
 
I don''t quite get the meaning of that.
It could mean to let other filters handle it, but that is exactly the
"continue" option.
 
Could someone explain how this option is used?
 
Thanks
