Vex is an eclipse plug-in editor for XML documents that works with Docbook and DITA doctypes. Vex hides the raw XML tags from the user, providing a word processor like interface.
In Eclipse Vex has it's own perspective that provides a panel for attributes of an element, an xpath status bar at the bottom of the editor that provides the current context within the document and an outline view of the major divisions.
In short, a nice XML editor for simple XML document creation.
