Inputs are the fragment table, the number of elements in the fragment table, and the number of words that make up nationality. The number of fragments (words) in a ship name dictate the possible sizes of ship type. If nationality takes one fragment, and ship type takes four fragments, then the minimum number of fragments in a composite ship name is: 5 = 1 (nationality) + 3 (ship type) + 1 (ship name) (same as 4 fragments (words) after nationality) This function starts at the longest possible series of fragments that might be ship type. This order is important becuase some ship types might begin with similar fragments: 'ship' and 'ship of the line'. Starting with the least possible series of fragments (1) would find 'ship' and make 'of the line' part of the italicized name.

The template does not render this correctly: The above renders without proper indents for items marked ** and ***. If the list is not wrapped in then the above list is rendered with bullets which is contrary to the Infobox ship usage guide. This code translates a bulleted list into an html unordered list: There are rules: 1. The parameter value must begin with a splat but may have leading and trailing whitespace. 2. Each list item after the first must begin on a new line just as is required by normal bulleted lists. 3. When adding a sublevel, the number of splats may increase by one and never more. This is illegal: *item ***item When any of these rules are violated, unbulleted_list returns the original text and adds the article to Category:WPSHIPS:Infobox list errors.

The params_t{} values are sequences where [1] is an index number that defines where in the rendering the label/value pair is positioned and [2] is the label that will be rendered when the parameter has a value. This indexing is used because params_t{} is not a sequence and because pairs does not necessarily return the 'next' k/v pair. This function spins through params_t{} and writes html for parameters that have assigned values into temp_t{} according to the 'index' value in the associated sequance table.
