In my server implementation I didn't implement this feature because I had remembered it as optional, based on IPP discussions.
If this feature retains its mandatory nature, then it raises several issues that we will need to resolve.
1) Suppose the client requests attributes-natural-language as one of the requested-attributes. If a job's natural language differs from the one in operation-attributes can the attributes-natural-language appear twice in the group, once in the first position to meet the rule under vote and a second time as a normal requested attribute. Otherwise, a printer must have special code to avoid sending attributes-natural-language twice.
2) Is attributes-natural-language really required to appear at the beginning of a job attribute group if the group does not contain job-attributes of type name or text.
