I also have the same doubt. Why do matchers behave different from other
components? For transformers, it is enough to say:
...
<map:transformers default="xslt" />
...
But for matchers, one has to declare:
...
<map:matchers default="wildcard">
<map:matcher name="wildcard"
src="org.apache.cocoon.matching.WildcardURIMatcherFactory"/>
</map:matchers
...
Cheers,
Sérgio
