[1] Chapter 18. Seam Text () https://docs.jboss.org/seam/latest/reference/html/text.html

Collaboration-oriented websites require a human-friendly markup language for easy entry of formatted text in forum posts, wiki pages, blogs, comments, etc. Seam provides the s:formattedText/ control for display of formatted text that conforms to the Seam Text language. Seam Text is implemented using an ANTLR-based parser. You don't need to know anything about ANTLR to use it, however.
