Output Ports

Port Description
result primary

The result document.

For every sentence element that contains one or more skippable elements, that is pagenum, noteref, annoref, linenum or math,

  • the skippable elements do not share any ancestors with other nodes in the sentence (nodes that are not themselves ancestors of the skippables), and
  • the sentence element has no (non-whitespace-only) child text nodes.

The reading order is preserved, and apart from elements that are broken up and wrapper span elements that are inserted, the structure of the DTBook is preserved.

skippable-ids
