Namespace-aware alternative to @Parameter PlexusConfiguration

Hi, I am writing a Maven plugin (for XQuery) whose should allow variables to be bound to XML fragments. Moreover, the variable names are XML QNames (like all names in XQuery), i.e., (URI, String) pairs. An example: http://www.w3.org/2005/xquery-local-functions;

Any specific requirements for extensions?

Folks, I am trying to write an extension for Maven Resolver which shall replace a default implementation. The implemented interface is an exported package in maven-core, the implementing class has proper javax.inject annotations @Named(...) and @Singleton so does the default (bundled) one.
