    Hi Uma,
    there is very important difference with admin tags.
    Admin tags have known formatting. Because of this it is possible to 
advertise a tag from implementation even if it doesn't support 
functionality which local network policy designates to the tag.
    Self-defined TLV does not have fixed formatting known beforehand. So 
only the implementation which is aware of its internals can originate 
and interpret it. For this reason it is more like Experimental or 
Vendor-Specific Sub-TLV.
