Processing instructions can be the replacement text of "processing instruction entities". These entities differ from other entities whose replacement texts are fully formed processing instructions: the text of a processing instruction entity can include non-SGML characters and the string chosen for the processing instruction closing delimiter. (The PIC delimiter closes a processing instruction. It is ">" by default.)
