Description

in xercesc/dom/impl/DOM(Attr/ElementNS)Impl.cpp queries for the "DOMPSVITypeInfo" feature interface are processed by returning the proper const xercesc::PSVIItem*.

To check interface existence the coresponding call to DOM(Attr/ElementNS)Impl::isSupported("+DOMPSVITypeInfo", NULL) should return true, which is actually returning false, because calls are redirected to xercesc::DOMImplementation::hasFeature.

note the requirement of the "+" before the "DOMPSVITypeInfo" in the call to DOM(Attr/ElementNS)Impl::isSupported("+DOMPSVITypeInfo", ...) which is required because xercesc::PSVIItem doesn't implement the xercesc::DOMNode interface as described in DOM3->Core->DOM Features.
calls to DOM(Attr/ElementNS)Impl::isSupported("DOMPSVITypeInfo", ...) without "+" should continue returning false;
