| The 'show' attribute is used to communicate the desired presentation |
| of the ending resource on traversal from the starting resource; it's |
| value should be treated as follows: |
| new - load ending resource in a new window, frame, pane, or other |
| presentation context |
| replace - load the resource in the same window, frame, pane, or |
| other presentation context |
| embed - load ending resource in place of the presentation of the |
| starting resource |
| other - behavior is unconstrained; examine other markup in the |
| link for hints |
| none - behavior is unconstrained |

| <annotation> |
| <documentation> |
| The 'actuate' attribute is used to communicate the desired timing |
| of traversal from the starting resource to the ending resource; |
| it's value should be treated as follows: |
| onLoad - traverse to the ending resource immediately on loading |
| the starting resource |
| onRequest - traverse from the starting resource to the ending |
| resource only on a post-loading event triggered for |
| this purpose |
| other - behavior is unconstrained; examine other markup in link |
| for hints |
| none - behavior is unconstrained |
