If there is no data in source the 'default' tag will be used.

If 'source' property is not defined in infobox markup, the 'default' is used and 'format' is ignored.

If there is some data in source the format tag will be used to adjust the data. It can be used for adding icons, links, additional text or launching parser functions.

'format' can hold near anything. We wanted to allow high flexibility inside this tag as based on our research this tag adresses the cases that frequently use the most user-built logic. Also this tag is meant for the more wikitext provicient user.
