The text area

A formatted text is placed into an editable multiline text area, hereinafter referred to as the "OE text area".

Your text and all the information about its internal structure (headings, tables, lists etc.) are stored in the form of XML code. The OE text area interprets this XML code and displays a structured text in accordance with XML tags instructions.

In other words, the OE text area contains an editable visualization of XML code as a formatted text.
