One minor issue I wonder about is how should we handle the OGR special
attributes (like OGR:LabelAngle) which currently haven't been retrieved only
when an explicit reference is used for the attribute in the mapfile. It
would be unwise to retrieve all the special fields along with the other
attributes if it's not required by the user.
We should probably have those attributes enumerated explicitly for the
driver by using a driver specific parameter in the query functions or a
driver specific processing option should be established for this purpose.
The latter is already there for the inline layers, which could be extended
here easily:

PROCESSING "ITEMS=itemname1,itemname2,itemname3"

This would also be essential if the user would define a subset of the
attributes to be retrieved so as to gain further performance increment of
the queries with certain data sources.

Best regards,
