Layer Virtualization and SDE

[Howard Butler]

Folks,

Attempting to compile up mapsde.c with USE_SDE defined in a post-RFC 
3 world has created an issue.  SDE has a function in it to return the 
index column for the table that someone has requested.  This function 
is called msSDELayerGetRowIDColumn.  This function prototype used to 
exist in map.h with all of the rest of the SDE functions.

After the virtualization, this prototype was removed from 
map.h.  This causes things not to compile, but the larger issue is 
that should there be a place holder for this type of thing in the 
layer virtualization?  Would other data providers potentially have a 
need to return which column is the index?

Please give me some advice on what to do.  Short-term, I can just 
stick the prototype in map.h and be on my way, but I'd rather things 
behave uniformly.

Howard
