If you have templates that match all the elemnts that appear in your
source the default template will not be used, otherwise it will be.
That happens in either style.


But if you filter on the template match you may need to add a new template when the schema changes or *a* default template will be invoked. If you filter on the invoking template no default template will be invoked.



Or by default do you mean any template with a * wildcard whether explictly in the stylesheet, as above, or the built in one?

I mean the inbuilt one or one explicitly in the stylesheet, it doesn't matter.





I find that handling different match patterns to handle the various special cases is a lot more manageable than using filters on the select. I mainly use the filter on select idiom if the filter involves a global parameter to the stylesheet, as XSLT1 restrictions disallowing variables in match patterns means that is often the best way. In XSLT2 this restriction will be dropped so I'd expect to use the match pattern version even more often.
