#2 is the way to go, but there's no such thing as specificity any more.

Here's what you're supposed to do:

Find the set of rules such that

1. The pattern on the template matches the node being processed, and

2. The mode on the xsl:template is the mode specified on the
xsl:apply-templates (or neither has a mode)

Then eliminate rules by importance (import order).

Then eliminate rules by priority.

Finally if there's more than one rule left, either give an error or
choose the rule that's last in the stylesheet; f there are no rules
left, use the built-in rule.

Concrete suggestions for wording changes to the spec that would make
this clearer are welcome.
