The GDL2 methods correspond to EOF 4.5.
http://developer.apple.com/documentation/LegacyTechnologies/WebObjects/WebObjects_4.5/System/Library/Frameworks/EOControl.framework/ObjC_classic/Classes/EOFetchSpecification.html

The GDL2 only declares fetchSpecificationByApplyingBindings:, it's not 
implemented.  This is a legacy method that the WO4.5 headers refer to 
(see -requiresAllQualifierBindingVariables). We've kept it as a 
placeholder in case someone relied on it and may need to implement it or 
if we find that it's needed internally.

Note that we are also still missing an implementation for 
-fetchSpecificationWithQualifierBindings:.  Contributions would be 
welcome, but if you need it, please ask and I'll see if I can shift 
priorities.

The GDL2 method is implemented and should correspond to documented behavior.

Neither EOQualifier nor EOFetchSpecification declare this method.  The 
proper method name is -initWithPropertyList:owner: and is declared in 
the EOPropertyListEncoding protocol.  The following classes declare this 
protocol: EOModel, EOEntity, EOAttribute, EORelationship, EOStoredProcedure.

Hope this helps and please let me know if there's something I can do to 
help wrt GDL2.
