	# According to "Introspection Data Format" of the DBus specification,
	# revision 0.30 [1], "Only the root <node> element can omit the node
	# name, as it's known to be the object that was introspected. If the
	# root <node> does have a name attribute, it must be an absolute object
	# path. If child <node> have object paths, they must be relative."
	#
	# The introspection XMLs of ModemManager object interfaces specify
	# name="/" at their root <node>, which should be omitted instead as the
	# object paths aren't fixed.
	#
	# CL:294115 [2] removed the name="/" attribute from those root <node>s
	# in several ModemManager introspection XMLs in order to allow
	# chromeos-dbus-bindings to properly generate the DBus proxies for
	# ModemManager interfaces. Instead of modifying those introspection
	# XMLs directly in the modemmanager-next git repository, we patch them
	# (all org.freedesktop.ModemManager1.*.xml, but not
	# org.freedesktop.ModemManager1.xml) here instead, which helps minimize
	# the difference between the local modemmanager-next repository and the
	# upstream repository.
	#
	# TODO(benchan): Discuss with upstream ModemManager maintainers to see
	# if it makes sense to apply the changes to the upstream code instead.
