Hi Xara Web Designer exports documents as XHTML and uses a transitional DOCTYPE allowing for W3C valid XHTML files to be exported.

The positioning of objects within the exported page is managed using absolute positioned divs. The program exports fixed width and fixed positioned pages. This means that a page will display the same size at any resolution.

Tags such as <p>, <h1> etc are only used for formatting and web crawlers will have no problems reading a page which does not use these tags.

Yes <ul> and <li> tags are used as a means of structuring navigation when creating css menus for for example but Web Designer provides you with button/ menu templates and you can create your own buttons too so navigation is handled within the program.

A web page does not need to have tables. Tables were originally made for data structure rather than layout and there are many advantages of using divs instead of tables

Hope this helps!
