I ended up writing a category for NSManager to deal with this using
the xattr.h APIs.

Something like:

- (NSDictionary *)PKG_extendedAttributesOfItemAtPath:(NSString
*)inPath error:(NSError *__autoreleasing *)outError;
- (BOOL)PKG_setExtendedAttributes:(NSDictionary *)inExtendedAttributes
ofItemAtPath:(NSString *)inPath error:(NSError *__autoreleasing
