I am sorry if my message upset you. However, I would point you to my actual words, which you do not seem to have read: "I live in hope and eagerly await next month's *draft* in the hope I will be proved wrong." I was under the mistaken impression from what had been said previously that the final text had to be sorted out in Sept/Oct for voting on by January. Such a schedule would not give us time for debate about requirements, which was one of my concern areas. I have previously noted that there were no adequate statement of requirements re interactivity prepared for the first draft, which seems to me to mean that there cannot be any such features until version 2.0, which will be at least a year after the 1999 date of Version 1.0. The revised timetable will make it easier to lobby for what is required to be put in Version 1.0, but not having seen any revision of the user requirements, or the first draft, it is very difficult for me to come to any clear determination. I would remind you that there is much other work held up waiting for the decisions of your committee. In particular I am unable to determine how much work is needed for interactivity control within the XML/EDI projects that are currently being proposed worldwide because of lack of guidance as to what the aims of the XSL committee are in this area. Once I know what you plan to do I can do something about explaining to an industry that is now keen to start actively exploring the role of XML what they can do with it. The XML/EDI community has a much wider need for interactivity than those currently being discussed by this list. Simply providing the functionality found in HTML forms or exsiting GUIs is *not* sufficient for this potentially very large user community. For electronic commerce you need to be able to extend the simple form creation specification currently being considered to do things like: a) check that the value entered in a form conforms to a predefined lexical value, or matches one of the entries in a referenced database (either on the local server, in cached memory or on a remote server) b) create menus whose lists of options can be created on-the-fly by selecting options from a referenced database c) allow the selection of one item in one menu to change the contents of another menu (e.g. if I select Supplier X then the list of options in the next menu changes to display only those items created by Supplier X) without having to make an additional call over the clogged network. d) allow sections of forms to be removed from, or added to, the display when a certain option is selected for a particular field. Most of these functions could be acheivable with a few extensions to ECMAScript, provided that this general purpose langaguage is adopted by XSL as the main means of associating programmable behaviour with XML elements. At present it is far from clear that this will be the case. My one big worry is that I will have to tell the XML/EDI user community "Sorry XSL cannot do what we need it to do, so we will have to develop our own interactivity control language, and drop the idea of using any features that may later on be standardized as part of XSL". At the moment this, unfortunately, looks to me to be the most likely scenario in the XML/EDI world. Martin Bryan XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
