WYSIWYM is an acronym for What You See Is What You Mean and refers to the paradigm for document editing. It is an alternative to the better known WYSIWYG paradigm.

In a WYSIWYM editor, the user writes the contents in a structured way, following their semantic value, instead of designing their aesthetic. For example, the user tells the editor that he is writing a title, a section, or an author. Because of this, one needs to know the structure of the document (contents semantic) before editing it.
