Xopus is a browser based in-place wysiwyg XML editor. Xopus allows users to edit XML data in an intuitive word processor like way while keeping the document valid. Item 1 Item 2 For an example of the combination of schema validation and an intuitive user interface select the two items in the list above and click the ordered list button.

Column 1	Column 2	Column 3
Row 1, Column 1	Row 1, Column 2	Row 1, Column 3
Row 2, Column 1	Row 2, Column 2	Row 2, Column 3
Row 3, Column 1	Row 3, Column 2	Row 3, Column 3
Row 4, Column 1	Row 4, Column 2	Row 4, Column 3

This example combines regular wysiwyg editing of a document with very controlled editing of semantic rich content. The main content can be edited like you would in a normal word processor. Though the difference is that the content remains schema valid XML because Xopus will not allow you to perform actions on the document that would render it invalid. The table is an example of controlled style. The style of the table is controlled by three attributes: alternaterowcolor, do all rows have the same color, or should the background color alternate? border, a limited choice of border styles. color, a limited choice of colors. You have quite some freedom to style the table, but you can't break the predefined style.
