OK, added the GDL2 one (libEOControl v4.2.38), need to find out where  
the SOPE one is used, likely not in any cases relevant for you.

Those are different methods. The ..Bindings methods replaces variables  
while the ..KeyMap method rewrites keys. Probably also used in the  
WebDAV layer only I guess. Need to move the keymap code to either  
NGExtensions or WebDAV.

For bindings we have in SOPE:
---snip---
- (EOFetchSpecification  
*)fetchSpecificationWithQualifierBindings:(NSDictionary *)_bindings;
---snap---
Which is marked "Yellow Box only" in WO 4.5 documentation:

   
http://developer.apple.com/documentation/LegacyTechnologies/WebObjects/ 
WebObjects_4.5/System/Library/Frameworks/EOControl.framework/ 
ObjC_classic/Classes/EOFetchSpecification.html

The WO docs do not specify anything like  
"-fetchSpecificationByApplyingBindings", I guess its a GDL2 only  
extension/bug. Anyway, added in EOControl v4.2.38.

Different thing again. EOQualifier/SOPE supports:
---snip---
- (EOQualifier *)qualifierWithBindings:(NSDictionary *)_bindings
  requiresAllVariables:(BOOL)_reqAll;
---snap---
as documented by Apple:
   
http://developer.apple.com/documentation/LegacyTechnologies/WebObjects/ 
WebObjects_4.5/System/Library/Frameworks/EOControl.framework/ 
ObjC_classic/Classes/EOQualifier.html

There is no such thing like "qualifierByApplyingBindings:" in EOF,  
probably a GDL2 only extension. Anyway, added in EOControl v4.2.38.

Where is this used? I think this is required for EOKeyValueArchiver?

Thanks for your help!
