ITALIC contains AST node holding the markup to be exported. You can access the whole exported parse tree starting from it (via org-element-parent/org-element-contents/etc) CONTENTS is the already exported (recursively) contents inside italic markup. For example, when you have /text, *inner bold*, [[file:link]]/, CONTENTS will contain everything inside properly exported into the target format. INFO is a plist containing exporter settings. It is used to pass around user customization like :with-title/:with-author and also the data that needs to be cached across individual transcoders (INFO can be modified in place) > Specifically, how do I obtain the contextual information that tells me > whether I'm a headline or in body? For example, (let ((first-child italic)) (while (not (org-element-type-p first-child '(headline inlinetask))) (setq first-child (org-element-parent first-child))) (org-element-secondary-p first-child)) -- Ihor Radchenko // yantar92, Org mode maintainer, Learn more about Org mode at <https://orgmode.org/>.
