I'm trying to add multiple dc:identifiers to a file (there are differing systems that refer to the same item), this does not appear to be possible. If two values are written, the first appears to be overwritten.
Is this expected behaviour, as I see nothing in the DC documentation that would suggest that this should be unique?
xmp-dc:identifier supports only a single text string
but xmp-xmp:Identifier supports multiple values.
See pages 33 and 35 of the July 2010 XMP specification, part 1 (http://www.adobe.com/content/dam/Adobe/en/devnet/xmp/pdfs/XMPSpecificationPart1.pdf).

Thanks Phil, that clears things up.
It's a shame that XMP doesn't follow the standard in this respect. I suspect adding dcterms as a custom namespace would also solve this.
