dsl file corruption by one of the builders

When working on my concurrent language, my .dsl file is regularly corrupted by a background task builder.


It replaces the content that has _name_, _ecore_, _k3_, _ecl_, and _metaprog_ keys by _ecore_ and _ale_ keys

Currently activated builders (`project` file) are:
```xml

org.eclipse.jdt.core.javabuilder




org.eclipse.xtext.ui.shared.xtextBuilder




org.eclipse.pde.ManifestBuilder




org.eclipse.pde.SchemaBuilder




org.eclipse.gemoc.xdsmlframework.ide.ui.GemocLanguageProjectBuilder




org.eclipse.gemoc.execution.concurrent.ccsljavaxdsml.ui.MoccmlLanguageProjectBuilder





org.eclipse.gemoc.xdsmlframework.ide.ui.GemocLanguageProjectNature
org.eclipse.gemoc.execution.concurrent.ccsljavaxdsml.ui.MoccmlLanguageProjectNature
org.eclipse.jdt.core.javanature
org.eclipse.xtext.ui.shared.xtextNature
org.eclipse.pde.PluginNature

```

Need to investigate which builder is doing this ...
