Comment 1 Laurent Goubet

This comes from the innards of the XML parser, meaning that the parsing of that Acceleo module failed somehow ("StructuralFeatures" not found probably means parsing of the property call "eStructuralFeatures" by OCL initially failed). However, without the module to check its serialization, the emtl file to check its XML validity or steps to reproduce, this cannot be investigated any further.
