Tested the code with the following commands.

$ ./run_tests tests/test_manifest_xml.py

For compatibility purposes across repo releases, all unknown elements are
silently ignored. However, repo reserves all possible names for itself for

reserved for that purpose, and repo guarantees to never allocate any
corresponding names.
A description of the elements and their attributes follows.
