MULTI String |
The text to be exhibited in a DMS panel follows the standard MULTIString - Markup Language for Transportation Information.
The Markup Language for Transportation Information (MULTI) is similar to HTML where text is transmitted, and tags define how the text appears (is displayed). Tags are enclosed within delimiters, contain an ID (one or more characters), and any optional parameters necessary for the tag.
Each MULTI tag begins with a left bracket ([), and ends with a right bracket (]). The tag ID appears after the left bracket ([), and is one or more case-insensitive letters. If the tag has any parameters, they immediately follow the tag ID and are case-insensitive (except where specified). No space or other separating character shall appear between the tag ID and the parameters. Some tags may operate in pairs, in which case the standard tag notation is defined as the opening tag. The opening tag defines where the tag's functionality begins. The closing tag defines where the functionality of the tag ends, and is defined as an opening tag with a forward slash preceding the tag ID e.g., the opening flash tag is “[fl],” and the closing flash tag is “[/fl].”
