I have an interesting thought...

Schema Map can have more than one object. (GW driver is the one that
shows this in the default config, and uses a rarely used token, Rename
Operation Attribute).

Can you have more than one map object, and say map everything but one
attribute, then have a second map object that maps additional attributes?

Are the cumulative? What if the same attr is mapped in both? Is the
latter in the list the one that takes affect?

Anyone know?
