It looks like there is a trailing null in the character data written inside the
XML box in JPEG
2000 (only tested with OpenJPEG).
I'm seeing a validation error in jpylyzer about not well formed XML, which I
think is
probably related to this. Or at least goes away with this change:

+ poBox->SetWritableData(static_cast<int>(strlen(pszXML)),
reinterpret_cast<const GByte *>(pszXML));
CPLFree(pszXML);
However that +1 looks deliberate. So is that trailing null intentional, in that
its required for
some interoperability or backwards compatibility reason, even though it isn't
strictly
allowed in XML?
