Subject: XSL Suggestion From: Paul Prescod <papresco@xxxxxxxxxxxxxxxx> Date: Sat, 20 Sep 1997 11:20:31 -0400 |
I would like to suggest that one of the development goals of XSL be that its declarative portion be as powerful as widely deployed declarative stylesheet technologies like those in Panorama, the SGML editors and so forth. I expect that there will be many environments where only the baseline declarative features of XSL will be implemented and users of those products should not be deprived of well-understood, easy to implement stylesheet features. I expect that the declarative portions will also be the only parts that are amenable to GUI modification and other forms of easily automated processing. Off the top of my head, the only common feature that the declarative subset of XSL is missing is some form of simple element numbering facility. I have always manipulated declarative style sheet facilities through GUIs, so I do not know if there exists a nice SGML-ish syntax for simple numbering. I would be curious if others have encountered such a thing (perhaps in FOSI?). I can't find an appropriate CSS spec., but I think that they were looking at counters which introduce linear dependencies and are thus not appropriate for XS. Perhaps something like <ELEMENT-NUMBER>, <CHILD-NUMBER>, and <ELEMENT-NUMBER-RECURSIVE> elements would solve 90% of the cases and the other 10% would need to resort to JavaScript.
