what's the difference between EnforcedSchema and DeterminedSchema

I've came across the notion of EnforcedSchema and DeterminedSchema in org.apache.pig.impl.logicalLayer.LOLoad.

Can anybody explain the differences between those two?

DeterminedSchema is the schema from the LoadFunc. EnforedSchema is only 
for debug purpose. This is how we fake schema and make test run in our 
test suite. In real situation, EnformedSchema is not being used.
