Subject: Rule conflict resolution From: Aneel Nazareth <anazaret@xxxxxxxxxxxx> Date: Thu, 05 Nov 1998 16:50:19 -0500 |
Hello all, I'm working on an XSL processor, and I have a question about conflict resolution for template rules. It seems to me that the precedence for template rules is static (independent of context). This means that the XSL processor should be able to simply sort the rules once and go down the list in order whenever rules are applied. This also means that, if the stylesheet author wanted to do so, she could sort the rules into the same order by hand ahead of time. My question is this: why not just keep the rules in the order that they are found (document order). (Presumably reverse document order, so you'd put general rules first and specific rules later, but that's beside the point). This allows the functionality of the current system, and also allows the user more control over the order of rule application, if desired. The Drawback that I see in this scheme is that it imposes a particular organization on the stylesheet, while the author might prefer to organize it differently. Are there other reasons to not do this?
