Thanks Johannes That is the way we have been using the term. We should probably make it explicit in our definition. Thanks for the DI clarification. Since we derive it from them it is good to have their blessing on that interpretation as well. Gregg -- ------------------------------ Gregg C Vanderheiden Ph.D. Professor - Ind. Engr. & BioMed Engr.

In retrieving a page, a user agent typically makes a number of HTTP requests - for style sheets, images, etc., after retrieving the XHTML, SVG etc., document that refers to them. If by "page" we mean just the XHTML or SVG document, then the statement in the WCAG 2.0 draft that delivery units and pages are often equivalent is correct; but I suspect that whatever people mean by "page" (an ambiguous term, admittedly), they wish to include at least some of the additional resources that are typically retrieved in separate HTTP requests after the document, in a markup language, is obtained." I had a problem with the definition, too. So I asked the DI group (<<http://lists.w3.org/Archives/Public/www-di/2005Aug/0001> >). According to the DI WG, a deliviery unit _is_ the result of a main request _and_ the additional requests automatically generated by the uaser agent. See Rotan's reply at <http://lists.w3.org/Archives/Public/www-di/2005Aug/0002.html>. Unfortunately, the DI glossary does not include this definition :-( -- Johannes Koch In te domine speravi; non confundar in aeternum. (Te Deum, 4th cent.)
