	If the PDF in question is compliant with any of the ISO PDF "subset  
standards" (PDF/X, PDF/A or PDF/E), then a conforming reader (aka  
rasterizer) is REQUIRED to process the embedded OutputIntent and you  
can NOT do any substitution...

	If the PDF is just a "generic PDF", then according to ISO 32000 (ISO  
PDF 1.7), the conforming reader may ignore the OutputIntent and/or  
substitute...
