Subject: RE: Can solve the N-queens - but can't count! From: Scott Boag/CAM/Lotus <Scott_Boag/CAM/Lotus@xxxxxxxxx> Date: Thu, 17 Jun 1999 01:18:43 -0400 (EST) |
The reasoning is so the templates can be processed as fragments, for applications like XML editors where an edit occurs and only part of the document needs to be updated. There are already several features (params, modes, etc.) that make this hard, but we think it is still feasible. Though it is fun to do things like N-Queens in XSLT, it's not really the design center for the language. Once you add for and while loops and mutable variables, you almost might as well use JavaScript or perl or the like. If we loose the ability for tools like editors to do fragment display, we have greatly diminished the uniqueness and viability of the language, in my opinion.
