Policy alternative selector
The Apache CXF policy engine supports different strategies to deal with policy alternatives. JBossWS-CXF integration currently defaults to the MaximalAlternativeSelector, but still allows for setting different selector implementation using the cxf.policy.alternativeSelector property in jboss-webservices.xml.

How? Googling for "cxf.policy.alternativeSelector" reveals a single link to the article above. Seems noone in the world has ever talked about this on the internet.
Looking at random jboss-webservices.xml files doesn't give me any hints as to how I would specificy this property.
