Description Ed Willink CLA 2020-05-09 03:20:31 EDT 
When loading /org.eclipse.ocl.examples.uml25/model/DI.xmi (the UML 2.5 underpinning for UMLDI) it contains

<xmi:XMI xmlns:xmi="http://www.omg.org/spec/XMI/20131001" xmlns:uml="http://www.omg.org/spec/UML/20131001" xmlns:mofext="http://www.omg.org/spec/MOF/20131001">
	<uml:Package xmi:type="uml:Package" xmi:id="_0" name="DI" URI="http://www.omg.org/spec/DD/20131001/DI">
....
	</uml:Package>
	<mofext:Tag xmi:type="mofext:Tag" xmi:id="_6" name="org.omg.xmi.nsPrefix" value="di" element="_0"/>
</xmi:XMI>

The known org.omg.xmi.nsPrefix mofext:Tag is converted to an Ecore Profile in the loaded UML. Ok

When saved again (using a ResourceEntityHandler to compress idrefs) we get

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xmi:XMI [
<!ENTITY _0 "http://www.omg.org/spec/DD/20131001/DC.xmi">
<!ENTITY _1 "http://www.omg.org/spec/UML/20131001/UML.xmi">
<!ENTITY _2 "http://www.omg.org/spec/UML/20131001/PrimitiveTypes.xmi">
<!ENTITY _3 "pathmap://UML_PROFILES/Ecore.profile.uml">
]>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:Ecore="http://www.eclipse.org/uml2/schemas/Ecore/5"
    xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:uml="http://www.omg.org/spec/UML/20131001">
  <uml:Package xmi:id="_0" name="DI" URI="http://www.omg.org/spec/DD/20131001/DI">
...
    <profileApplication xsi:type="uml:ProfileApplication" applyingPackage="_0">
      <xmi:Extension extender="http://www.eclipse.org/emf/2002/Ecore">
        <eAnnotations xsi:type="ecore:EAnnotation" source="http://www.eclipse.org/uml2/2.0.0/UML">
          <references xsi:type="ecore:EPackage" href="&_3;#_z1OFcHjqEdy8S4Cr8Rc_NA"/>
        </eAnnotations>
      </xmi:Extension>
      <appliedProfile xsi:type="uml:Profile" href="&_3;#_0"/>
    </profileApplication>
  </uml:Package>
  <Ecore:EPackage base_Package="_0" nsPrefix="di"/>
</xmi:XMI>

The save correctly uses xmlns:uml="http://www.omg.org/spec/UML/20131001" but fails to reverse the Ecore Profile back into a org.omg.xmi.nsPrefix Tag and fails to remove the unwanted profile application. The OMG namespaces are therefore polluted by Eclipse UML namespaces.
