At present, TOCs are only generated for documents which have multiple <text> elements. This is resulting in documents which should never have multiple texts being created that way, just so they get an automated TOC. Obviously this is silly, and I need to revise the system so that it continues to support the existing documents (while we change them -- although perhaps not all will change), but supports TOC generation for single-text documents based on some measure of complexity. (Or perhaps all documents with multiple div elements should get a TOC by default?)
