Hello,

I have defined a simple metamodel using Ecore and I have generated the plugins. When I create a model conforming to that metamodel, the serialized thext looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<Library xmlns="http://sLibMM"; xmlns:_="" _:name="theLibrary">
  <Book ref="1" available="no">
    <title>myBook</title>
    <author>me</author>
  </Book>
  <Book ref="2" available="no">
    <title>yourBook</title>
    <author>you</author>
  </Book>
</Library>

And I would like it to be:

<?xml version="1.0" encoding="UTF-8"?>
<Library name="theLibrary">
  <Book ref="1" available="no">
    <title>myBook</title>
    <author>me</author>
  </Book>
  <Book ref="2" available="no">
    <title>yourBook</title>
    <author>you</author>
  </Book>
</Library>

That is, I don't want the xmlns attribute in my XML.
Any idea how can I do it?

I attach my Ecore metamodel.

Thanks in advance.

Ander
