The tag properties view is an alternative method for setting the attributes in a tag. Its shows every legal attribute for a tag, based on the DTD in use, and allows you to enter/select the value for those attributes. Pressing enter/return in each text area will insert that attribute. Using this view you can easily enter all the attributes for a tag that you want without having to type them all in the editor.
Requires that the DTD in use is parsed correctly.
