I love how it says:

[...] A format which includes rarely used options is
likely to cause interoperability problems [...] The
format defined below includes only one rarely used

Which reminds me of when svn started to report fractions of seconds in
their ‘svn log --xml’ output, causing a few log visualizers to break :)
