Hmmm... this is difficult. We are generating a very complex document (many pages, different styles, etc.) from a Drupal 8 site. The Word file is the output of a complex Twig template, that includes many entity_references, and; therefore, a complex relationship of different Twig templates get embedded. We can't really use the code feature of phpdocx, as our team doesn't have sufficient PHP/Drupal coding experience.
Thinking about future development, would it be possible to do something like have an opening and closing phpdocx tag that integrates the call to $docx->embedHTML($html, array('useHTMLExtended' => true)); when the closing tag is called?
Effectively, this would use everything between the opening <phpdocx_section> and </phpdocx_section> is the value of $html. Something like:
<phpdocx_section data-paperType="A4-landscape" data-sectionType="nextPage">

</phpdocx_section>
Might this allow for using HTMLextended to achieve multiple sections in a document?
