The schema bean-deployer_2_0.xsd redefines types in jboss-beans-common_2_0.xsd, essentially transferring them to the namespace of the former. However, the <redefine> construct in the former schema refers to types, such as "searchType", which are not defined in the latter schema, which is a violation of the XML Schema 1.0 spec for <redefine>. This prevents validation of instance documents, such as jboss-logging.xml, since one of the schemas it depends on is thus invalid.
