| 23 Include or exclude elements which depend on a specific Docutils component. | |
| 24 | |
| 25 For use with `nodes.pending` elements. A "pending" element's dictionary | |
| 26 attribute ``details`` must contain the keys "component" and "format". The | |
| 27 value of ``details['component']`` must match the type name of the | |
| 28 component the elements depend on (e.g. "writer"). The value of | |
| 29 ``details['format']`` is the name of a specific format or context of that | |
| 30 component (e.g. "html"). If the matching Docutils component supports that | |
| 31 format or context, the "pending" element is replaced by the contents of | |
| 32 ``details['nodes']`` (a list of nodes); otherwise, the "pending" element | |
| 33 is removed. | |
| 34 | |
| 35 For example, the reStructuredText "meta" directive creates a "pending" | |
| 36 element containing a "meta" element (in ``pending.details['nodes']``). | |
| 37 Only writers (``pending.details['component'] == 'writer'``) supporting the | |
| 38 "html" format (``pending.details['format'] == 'html'``) will include the | |
| 39 "meta" element; it will be deleted from the output of all other writers. | |
