The icons on the left margin alow you to create a new XML element definition, create a new attribute, create a modifier, create an element reference, add a #PCDATA, create a general entity, create a parameter entity, create a parameter entity reference, insert text, insert notation, or insert a comment. A context menu alows you to click on the tree and perform operations on a selected DTD node such as move up/move down, rename, and so on. A Properties window (lower right) shows all of the associated properties of a selected node (name, type, restrictions, content type, default, and so on). Once completed, you can easily assign the DTD to an XML instance document for easy XML editing and validation.
