If set to true, tehe metadata writer will omit writing a DEP-11 header document when in YAML mode, and will not write a root components node when writing XML data.
Please keep in mind that this will create an invalid DEP-11 YAML AppStream collection metadata file, and an invalid XML file. This parameter should only be changed e.g. by the appstream-generator tool.
NOTE: Right now, this feature is only implemented for YAML!
