The documentation for both text markup and TeX-style LaTeX fragments states that their contents (CONTENTS for text markup, BODY for TeX-style LaTeX fragments) cannot span more than three lines, but I'm not seeing such limitation for either in practice. I don't know if this is a documentation error or a parser error.
