A component that uses catalogs for resolving entities.
This component simply inherits from the excalibur implementation and
adds the context: protocol to each relative uri.
The catalog is by default loaded from "WEB-INF/entities/catalog".
This can be configured by the "catalog" parameter in the cocoon.xconf:
<entity-resolver>
<parameter name="catalog" value="mycatalog"/>
</entity-resolver>
