what's a standards track control?

[Bruce Greenblatt <bgreenblatt@directory-applications.com>]

What does it mean for an RFC that defines an LDAP control to be Standards 
Track?  Since it clearly isn't a requirement that all LDAP Servers to 
implement the control, I wonder what the difference is between a "Standards 
Track" control and an "Informational Track" control.  If there is no 
difference, shouldn't all controls be Informational Track (or maybe 
Standards Track)?  Or maybe, all Standards Track controls should be 
mandatory to implement, once the RFC reaches a Standard status.  Any thoughts?
