Parameter syntax:

[ '[all]' | '[lookupInclusion]' ]?

When option [all] is specified, this command untranscludes all the included nodes found in the document being edited. Untranscluding means: replacing some included nodes by the corresponding inclusion directive (e.g. xi:include element).

Otherwise, this command replaces the selected included nodes by the corresponding inclusion directive. Unless option [lookupInclusion] has been specified, one of the topmost included nodes must be explicitly selected. If option [lookupInclusion] has been specified, the selection, or even just the caret, may be anywhere inside the included nodes.
