WYSIWYM (what you see is what you mean) is an alternative paradigm to WYSIWYG, in which the focus is on the semantic structure of the document rather than on the presentation. These editors produce more logically structured markup than is typical of WYSIWYG editors, while retaining the advantage in ease of use over hand-coding using a text editor.
A structure editor, also structured editor or projectional editor, is any document editor that is cognizant of the document's underlying structure.Structure editors can be used to edit hierarchical or marked up text, computer programs, diagrams, chemical formulas, and any other type of content with clear and well-defined structure.
