No need for a new PROCESSING directive, the documented way to connect to 
OGR data sources is to use:

LAYER
    ...
    CONNECTIONTYPE OGR
    CONNECTION "<datasource_name>"
    DATA "<layer_definition>"
    ...
END

http://mapserver.org/input/vector/ogr.html#using-ogr-data-sources-in-the-map-file

The question is really whether we should keep the undocumented shortcut 
(CONNECTION "<datasource_name>,<layer_definition>") which was likely 
introduced to support TILEINDEX on OGR data sources.

Maybe Frank can comment if he reads this.
