You've got some pretty deep misunderstanding of what goes in the "match"
attribute, because two of us have tried to explain your mistake and somehow
you haven't grasped it.

You might find this little tutorial on patterns helpful:

http://www.saxonica.com/documentation/patterns/intro.html

Note also that xsl:apply-templates does not have a match attribute, it only
has a select attribute.
