If it's a performance question then the answer depends on which processor
you're using. There's unlikely to be a big difference, and you'll only find
out which is faster by measuring it. In Saxon there's almost certainly no
difference, since a template rule with match="a|b" is essentially compiled
into two rules match="a" and match="b" that point to the same template body.
It might be fractionally faster to do match="*[@type=('a','b')]" (that's 2.0
syntax) but I doubt it's noticeable.
