RGH: Best-effort is the only attribute whose value affects the processing
RGH: of other attributes while the Printer is acquiring the attributes
RGH: from the operation.

RGH: If best-effort remains an attribute, an implementation must acquire the
RGH: value of best-effort before it validates any other attributes.  This is
RGH: a constraint which may or may not cause implementors a problem, but it
RGH: does create a potential look-ahead problem.  

RGH: If best-effort becomes a parameter, it will always precede all
RGH: attributes, leaving more flexibility for the implementor.  I prefer a
RGH: design that avoids look-ahead problems as much as possible.
