As far as I could see, this is already supported in exiv2 - it mainly requires the wrapping of the namespace registration methods, after which the current methods should be able to read/write tags in a custom XMP namespace:
static void registerNs (const std::string &ns, const std::string &prefix)
Is there any news about that in the current versions? I would like to add my voice to the wishlist motion. :)
