Thank you @regexident, I'll update the sample XML to the new version in master, which is no longer stored in .xml file. I had to change that in #18 as generation of Jazzy docs fails because of cruft accumulated in XMLCoder.xcodeproj. We have to regenerate the project file with swift package generate-xcodeproj. This auto-generation misses files that don't have .swift extensions unfortunately, which means we have missing sample XML file in the test bundle. The sample XML was moved to the .swift file from .xml file.
