hand over "ASIN" within OPF-FIle ?

[Gru0810]

I use opf-File to transfer Infos to ABS. With this way I'm able to transfer the "ISBN" by using the following line in opf-File:
<dc:identifier id="BookId" opf:scheme="ISBN">9783844541236</dc:identifier>

I tried following line :
<dc:identifier id="BookId" opf:scheme="ASIN">3844541357</dc:identifier>
But ABS did not grab the content.
What is the best way handover the "ASIN"?

This is not supported for OPF file but I created a feature request for it #1330
