I know that there is an option to add standalone='no' or standalone='yes' attribute in the XHTML document's header (uhm, or is it property in XML's case ??); AFAIK this is called DTD, but I am not sure if the last "D" stands for declaration or or definition. If you want to, see the example of the full code in my own home-site's source: http://tadej-ivan.50webs.com ... Anyway, I am interested, does this applies to any "external files" (on which XHTML document depends), like for instance JavaScript scripts, CSS external style files etc., or just to XHTML-related ones, i.e. the external XML schemas ?? Oh and optionally for the problem that I had with understanding the basic principles of XML/XHTML (well, actually it was understanding XML schemas in particular), see the A XML related confusion; a theoretical question once again ... thread (of course, only if you are interested) that I've opened on Ars Technica forum back then. P.S. -- Please note that I've posted this same topic in the "HTML & Website Design" part of DP-forums because I wasn't sure which one is the correct one !! tayiper
