Template:Flag data/doc

is an internal data container not intended to be transcluded directly. It is used indirectly by templates such as,  , and others.

This template is transcluded if a flag template is used without the first parameter, or with an empty first parameter. It can be used to place an "invisible" flag icon, as an alternative to using noflag (which adds a tag with padding at the size of a flag icon), if one item in a list of items with flags shouldn't have a flag icon. For example: which looks the same as
 * Gibraltar

Comparison: with and without flag

 * Gibraltar – internally transcludes Flag data
 * 🇬🇮 Gibraltar – internally transcludes Country data Gibraltar
