A question arose in the forums – when importing HTML content using altChunk, can you cause KeepLines \/ KeepNext to be set for imported paragraphs. This is not possible. You can control this when importing a WordprocessingML document using altChunk – you simply go into the imported document and set keepLines (section 17.3.1.14 in IS29500) \/ keepNext (section 17.3.1.15), and when Word imports that content, the resulting paragraphs have their keepLines \/ keepNext set per the imported content. However, there is no analogous markup for HTML, so there is no way to set those child elements of the paragraph properties element.<\/p>\n

However, it is straightforward to insert a page break between imported chunks of content. The following example sets up a document with two imported chunks, with a page break inserted between them.<\/p>\n
