No, I only use it to find, if any, a "piece of knowledge" b with 
a.le?(b).
Toy examples :
"birthday" <= "birthday John in March" <= "birthday John 15th March"...
So, for Persons : MIN <= John <= John Doe <= John Doe phone=12345 <=...
for Dates "MIN <= March" <= "15th March" <= 15th March 9pm ...

See above for MIN. MAX happens for instance when you freeze a knowledge 
and then modify it. Or when you know too much : "birthday 15th March and 
2d April"...

All the best,

Michel
