Hi Paul. I broadly agree with the points you raise, areas where I differ are largely a matter of personal taste, and these sorts of differences basically boil down to individual developers prefered methodology. I wanted to ask you further about your conclusion. Don't we face here an issue whereby it would be mroe appropriate to have either a different namespace for producing say aural "renderable" output that might be produced along side the FOs, or the use of different stylesheets for different media. Specifying a different stylesheet PI for each media covered would seem to be best. Now that we have managed to seperate data from presentation, able to provide differing views of the data as appropriate, if we look for generic catch-all presentation languages don't we run back into the arms of some of the probelms we faced with HTML.... does pretty much everything, but nothing very well? As a side note.... most people browsing the Web are most concerned with the appearence of the Web app they are using and the functionality provided.... not the source code used to render it, and I beleive that it is not worth while sacrificing the functionality provided by clean domain specific FOs (or other media specific objects), so that people have a better time of viewing source. If one is that concerned about seeing the original data one can go fetch it. Continuing on from this point about availability of original data, I have just come back from an eXcelon seminar, and one of the key concerned raised was the fact that core data is exposed to the client... a lot of companies do not want core data exposed directly to the client.... consider the concept of data syphoning combined with Web crawlers, and it is easy to see why this is a concern for companies. It is also easy to forget that we will have XHTML, and we already have XML+CSS, and nobody is suggesting that XSL is a direct competitor for these across all solutions. It is likely that most Web sites will present in either XHTML or XML+CSS. If presentation semantic is required as part of a solution there are already means for implimenting this. If however this is either not a concern, or the richist presentational expression possible is a requisite, then I feel that FOs are absolutely the way to go, not a watered down formatting semantic.
