ModeShape does not allow importing a XML file that declares a default XML namespace

      Write a simple XML file, such as:

      <?xml version="1.0" encoding="utf-8"?>
<root xmlns="http://www.ns.com">
    <element>value</element>
</root>

      Then, in your code, register the default namespace's URI with the workspace namespace registry, as follows:

         NamespaceRegistry nsR = session.getWorkspace().getNamespaceRegistry();
   nsR.registerNamespace( "ns", "http://www.ns.com" );

      Then, import the XML file under some JCR node of your repository, as follows:

         InputStream input = new FileInputStream( xmlFile );
   session.importXML( n, input, ImportUUIDBehavior.IMPORT_UUID_CREATE_NEW);

      The call to the importXML() method raises the following exception:

      javax.jcr.RepositoryException: Prefix  is already permanently mapped

      But the XML default namespace declaration should be simply ignored, since a JCR namespace which is mapped to the same URI already exists.

    Description

      When importing a XML file (using the Session.importXML() method) that declares a default namespace (xmlns="URI"), you get the following error:

          javax.jcr.RepositoryException: Prefix  is already permanently mapped

      This makes sense since JCR always creates a JCR namespace identified by the empty prefix. And according to the JCR specs:

      For each XML namespace declaration with prefix P and URI U:
      a. If the namespace registry already contains a mapping of some prefix P' to U (where P' may or may not be equal to P) then the namespace registry is left unchanged."

      The code should discover that the default namespace does not match a registered namespace and it should therefore register it and use this for the XML default namespace rather than throw the exception.
