| * user a flat list of all model elements that require a manual merge. |
| * <p> |
| * There are a couple of open issues here: |
| * <ol> |
| * <li>All the model provider UI is Common Navigator based so there is no model |
| * provider contributed actions available to overwrite and mark-as-merged. This will |
| * be a problem for models that have multiple resource mappings within a single file. |
| * <li>The order in which model elements are merged may matter. There is currently |
| * no Team API to determine this order.</li> |
| * <li>This operation assumes that a compare input will be available for the |
| * model objects that are obtained from the model provider. Although this |
| * is a reasonable assumption, it is not enforced by the API specification.</li> |
