> Yes, I know, that the version in catalog shall be used to determine version
> and therefore the version COSDocument#getVersion() method result is expected
> to reflect that. But I ask the header string. And it's result differs from
> the actual header string in the file after PDFParser finishes its job.
> Please, bear also in mind that Extensions Dictionary (see ISO 32000-1
> chapter 7.12) validation should consider the values both in document catalog
> and header:
> "The value of BaseVersion, when treated as a version number, shall be less
> than or equal to the PDF version, both in the document header (see 7.5.2,
> "File Header") and the catalog Version key value, if present."
> As it says "both", that means BaseVersion may not exceed the value neither
> in header nor in catalog, therefore we need to validate that. 
> {quote}
> my answer:
> How about something like this:
> {code}
> private String originalHeaderString = null;
> public void setOriginalHeaderString(String header)
>     {
>         if (originalHeaderString != null)
>               throw bad state exception blah blah
>         originalHeaderString = header;
>     }
> public String getOriginalHeaderString()
> {
>     return originalHeaderString ;
> }
> {code}
> The setter should be called only once by parseHeader().
> This was accepted, so I'll implement it (for 1.8 only)
