The Eclipse XML/XSD validation system is reporting the following error:
src-resolve.4.1: Error resolving component 'excluded-attribute'. It was detected that 'excluded-attribute' has no namespace, but components with no target namespace are not referenceable from schema document 'file:///bridge-impl/src/main/resources/META-INF/liferay-faces-bridge-2.0-extension.xsd'. If 'excluded-attribute' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'excluded-attribute' has no namespace, then an 'import' without a "namespace" attribute should be added to 'file:///bridge-impl/src/main/resources/META-INF/liferay-faces-bridge-2.0-extension.xsd'.
In order to fix, the excluded-attribute and public-parameter-mapping references must be prefixed with the bridge: namespace.
