I am not sure, if you mean caption package can insert pdf literals as per the specifications in Section 10.8.2 of PDF Reference Manual 1.7 which is about alternate descriptions with /Alt entry. I could not find anything like that in the caption package, am I missing something?  The example 10.23 of PDF specification wants the following coding scheme (Page 943, Section 10.8, Accessibility Support):

/Span << /Lang (en-us) /Alt (six-point star) >> BDC (✡) Tj EMC

The macros which I had provided in my previous mail does exactly the same. But as Ambika had reported, it was not recognized by Acrobat Pro, unfortunately.
