jboss-web_8_0.xsd Eclipse validation errors

src-resolve.4.2: Error resolving component 'javaee:string'. It was detected that 'javaee:string' is in 
 namespace 'http://xmlns.jcp.org/xml/ns/javaee', but components from this namespace are not 
 referenceable from schema document 'file:///home/eskimo/workspace/javaee-mars/a1/WebContent/WEB-
 INF/jboss-web_8_0.xsd'. If this is the incorrect namespace, perhaps the prefix of 'javaee:string' needs to 
 be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:///
 home/eskimo/workspace/javaee-mars/a1/WebContent/WEB-INF/jboss-web_8_0.xsd'.

src-ct.2.1: Complex Type Definition Representation Error for type 'symbolic-linked-allowedType'. When
 <simpleContent> is used, the base type must be a complexType whose content type is simple, or, only if
 restriction is specified, a complex type with mixed content and emptiable particle, or, only if extension is
 specified, a simple type. 'boolean' satisfies none of these conditions.
