actually, i have in mind "chunking" like this: a chapter-header should not appear in the middle, or at the bottom, of the viewport. initial text after a chapter-header should appear in the same viewport as that header. the first line of a paragraph shouldn't be split across viewports from the rest of the paragraph. the last line of a paragraph should not be split across viewports from the rest of the paragraph. an image should not be split across a viewport. a caption for an image should appear in the same viewport as the image itself. the table-header for a table should not be split across viewports from the table itself. a table which will fit entirely within the current viewport should not be split across viewports. the caption for a table should not be split across viewports from the rest of the table. a blockquote should not be split unnecessarily across viewports if it'll fit on a single viewport. a list should not be split unnecessarily across several viewports if it would fit on a single one. a description term should appear on a viewport with its description definitions, to the extent possible. the last paragraph of a chapter shouldn't appear on a separate viewport from the rest of the chapter. any two contiguous chunks of text which refer to each other should be shown on the same viewport. the cover-page for a document shouldn't be split across multiple viewports, if at all possible. a dedication page shouldn't be split across viewports.
