it's been rejected, because it's not clear what it means in all contexts.<br>
For example, does it used when rendering to screen? What about if the<br>
screen is simulating a printer (aka "Overprint Preview")?? etc. etc. etc.<br>

If there are rendered elements that don't apply (because they are not<br>
in the intended device profiling space, or the actual device space<br>
is not the intended device profiling space), you have the usual options:<br>
<br>
Reject the file.<br>
Ignore those elements (don't render them).<br>
