| * <li> Specific output locations (specified on source entries) can be null, if not they must be located inside the project, |
| * <li> A project entry cannot refer to itself directly (that is, a project cannot prerequisite itself). |
| * <li> Classpath entries or output locations cannot coincidate or be nested in each other, except for the following scenarii listed below: |
| * <ul><li> A source folder can coincidate with its own output location, in which case this output can then contain library archives. |
| * However, a specific output location cannot coincidate with any library or a distinct source folder than the one referring to it. </li> |
| * <li> A source/library folder can be nested in any source folder as long as the nested folder is excluded from the enclosing one. </li> |
| * <li> An output location can be nested in a source folder, if the source folder coincidates with the project itself, or if the output |
| * location is excluded from the source folder. </li> |
| * </ul> |
| * </ul> |
| * |
| * Note that the classpath entries are not validated automatically. Only bound variables or containers are considered |
| * in the checking process (this allows to perform a consistency check on a classpath which has references to |
| * yet non existing projects, folders, ...). |
| * <p> |
| * This validation is intended to anticipate classpath issues prior to assigning it to a project. In particular, it will automatically |
