XML is not the only alternative - please don't use it as a straw man.
For example, here is a fragment from the Bacula docs using their
hierarchical format:

FileSet {
Name = Test
Include {
File = /home/xxx/test
Options {
regex = ".*\.c$"
}
}
}

Or here is a piece from the buildfarm client config (which is in fact
perl, but could also be JSON or similar fairly easily):

mail_events =>
{
all => [],
fail => [],
change => ['foo(at)bar(dot)com', 'baz(at)blurfl(dot)org' ],
green => [],
},
build_env =>
{
CCACHE_DIR => "/home/andrew/pgfarmbuild/ccache/$branch",
},
