/**
* With Spring 3.1, bean id attributes (and all other id attributes across the
* core schemas) are no longer typed as xsd:id, but as xsd:string. This allows
* for using the same bean id within nested <beans> elements.
*
* Duplicate ids *within the same level of nesting* will still be treated as an
* error through the ProblemReporter, as this could never be an intended/valid
* situation.
