Error description

• After updating a BPMN model's documentation, saving the change,
  closing and reopening the model, pink rectangles with the
  'Invalid view' message appear on the diagram and HTML reports
  are generated with the message: 'org.xml.sax.SAXParseException:
  The entity name must immediately follow the '&' in the entity
  reference.'
  
  The root cause of the problem is that model elements have names
  with the ampersand ('&') character.  After changing and saving
  the BPMN model, the '&' is replaced by the ASCII code value,
  namely '%26', wherever there are references to other BPMN
  models.
  
  Workaround: Refrain from using the ampersand character in your
  BPMN models that have dependencies to other models.

  ****************************************************************
  When a model containing event names like "Task ? product" is
  modified and saved, the model opens with an exception when
  closed and opened.
  

Problem conclusion

• The parameter OPTION_SKIP_ESCAPE_URI was set to its default
  value(true) during save, which was skipping characters like
  "?". Setting it to false solves the issue.
