Deep Content Splitting Overview
Deep content splitting allows published output to have page breaks within structures such as table rows, boxed areas and alignment groups. Deep content splitting is especially useful when used with documents containing deep rows. With deep content splitting enabled Arbortext Editor can correctly format the page by breaking within the row itself, moving the remaining row content to the following page.
The following limitations apply to the deep content splitting:
Splitting of tables with long vertical spans — Deep content splitting is done in Pubtex’s output routine by analyzing and altering the galley that makes up the final page candidate. Since vertically spanned cells are attached to the last row that they span, it is possible that a long spanned cell will not even be part of the galley gathered for a page. Therefore, there is no cell to split.
Splitting of tables with repeating headers and footers — Repeating headers and footers are supported in outer tables, but not in nested tables.
Change bars — Deep splitting pages with change bars is not supported.
Line numbering — The multiple formatting passes necessary for deep content splitting are incompatible with Line Numbering.
Footnotes — It is possible in the case of a table with multiple footnotes that the footnote numbering will be incorrect after deep content splitting. For example, if a table row has several cells containing footnotes, and a split occurs between those footnotes, there is no way to reorder the numbering on the page.
Gentext (Marks) — Similar to footnotes, it is possible for marks to be out of order after a page is split.
You can also set deep content splitting for a particular region of a document by selecting that region and inserting a _deepsplit tag pair by choosing Format > Touchup > Deepsplit Region.

Using line numbering with deepcontentsplitting may produce unexpected results. It is recommended that you do not use line numbering with deepcontentsplitting.
