The jboss-web_7_2.xsd file cause validation errors in eclipse.

The following error from line 261:
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

This also happens in jboss-web_7_1.xsd
