Dublincore schema of versions should not be writable

I am able to make changes to archived/versioned documents via CMIS. I have tried with both a JavaScript CMIS library as well as the Apache Chemistry Workbench.

The simplest test I have been able to perform:

• Launch a plain Nuxeo 7.1 server with no Studio project installed
• Create a workspace
• Drag and drop a file (I used a PDF)
• Edit the PDF to create a version.
• Get the id of the version (e.g. Export as XML or just use the Workbench)

Then I used a GroovyScript from the Workbench console to modify the version without issue:

def someDoc = session.getObject("aeda9f85-a775-42d6-957d-908cd9b8432b")
def props = ['dc:description': 'this was modified with the Workbench.']
someDoc.updateProperties(props, true)

I verified that the version was modified, not the Live Document, using the History tab in Nuxeo to view the version (and Export as XML because dc:description isn't displayed by default for Files).

I tested with Nuxeo 7.1 and Workbench 0.12.0. I tried Atom and Browser bindings.
