RE: <xsl:apply-imports> and rules with higher priority
For most applications, I think <xsl:next-match> is more likely to do what you want than <xsl:apply-imports>. It's certainly easier to understand. xsl:next-match simply defines an ordering of all the template rules for a mode, ordered first by precedence, then by priority, then by document order; it finds the current template in that list, and calls the next one down the list that matches the current node. xsl:apply-imports is a bit more complicated; it only considers rules in an "imported stylesheet layer", where a layer means a stylesheet that you import, plus all modules that include or are included by that module. The big advantage of next-match is that it allows you to invoke lower-priority templates in the same module.
