Can you post the whole document? Where is the schema that you're 
validating against?

The error is reported as being in line 2 because that is the start of the 
METS container, which apparently doesn't have any PREMIS elements. To fix 
the error, you wouldn't necessarily have to change line 2. But that is how 
to read the error message.
