Are those namespaces defined within Exiv2, or within the XMP files? I.e. are the
URI's that play a role here defined within Exiv2 or by the program that wrote
the XMP (in this case lightroom)? As I understand namespaces, having them
defined within the library that reads the data would defeat portability of XML
And when I look at a Digikam sidecar, I see a bunch of lines of the form
xmlns:<prefix>="<URL>" with the prefixes then used later in the different data
In this case, if LR indicates a non-existing or wrong namespace, of course
Exiv2/Digikam will have a problem...
