Description Stephan Eberle CLA 2011-06-07 08:19:50 EDT 
= Problem description =
XML files with OMG XMI content yield an OMG-defined XMI namespace rather than the model namespace but still may embed model content somewhere inside:
 
<xmi:XMI xmi:version="2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML">
  <uml:Model xmi:id="bdcfbaeb-2732-446b-946e-0656c4efb96c" name="Model">
    ...

For the sake of optimizing content type detection performance, MetaModelDescriptorRegistry#fastGetContentTypeId() considers such files as non-model files and returns IExtendedPlatformConstants.CONTENT_TYPE_ID_NON_MODEL_XML_FILE as content type.

= Resolution proposal =  
Make sure that MetaModelDescriptorRegistry#fastGetContentTypeId() excludes OMG XMI files from the performance optimization, and lets perform a full content type analysis so as to find out if the OMG XMI file is a model file or not.
