Highlight syntax

When text is enclosed in a pair of single or double hash symbols (#), and no role is assigned to it, the text will be rendered as highlighted (aka marked) text for notation purposes.

When Example 1 is converted to HTML, it translates into the following output.

Example 2. Highlighted text HTML output
