[pure virtual]

Sets the actual directory where user defined coordinate system definitions can be found or can be written into. The directory set through this method must exist and writeable. If set to an empty string, the catalog's 'user defined coordinate system' directory will be unset and any updates will again happen only inside the directory as returned by GetDictionaryDir().
