[pdftex] PDF/X1a

The new LSI printing specs require that a book block be set at PDF/X-1a or
PDF/X-1a:2001, an old standard dating back to 2001.  Ironically this is 
necessary for one to use their newest OCE printer. pdftex files use a 
different notation, on my copy PDF-1.4. It may be that LSI is looking for the  
exact string PDF/X-1a in the pdf file. 

Two problems. First we are dealing with two different notations. Second, 
PDF-1.4 may not be correct and PDF-1.5 may be the equivalent.  
Does anyone have any clarification on this?
