If users create long articles in word, then paste them into eZ the article often 'fails to save'. If the user copy, pastes & saves in small chunks the same woc - the article is typically successfully saved.

Given the lack of auto-save and general stability issues, all content is currently drafted in word first. Therefore, this is a common use case for us.

Steps to reproduce:

1. Start creating a new article
2. type something on the intro field, since it is required
3. Paste the contents of the attached test_paste.docx on the body of the article
4. Click Save

On Windows, using Microsoft Office, the following error is displayed on the console:

{"ErrorMessage":{"_media-type":"application\/vnd.ez.api.ErrorMessage+json","errorCode":406,"errorMessage"
:"Not Acceptable","errorDescription":"Argument '$xmlDoc' is invalid: Transformation of XML content failed
: Error in 0:0: Unhandled link type"}}

Reproduced on eZ Enterprise 1.5.1, with Chrome and Firefox.
