Probably. There was some discussions on it lately.

Is there a specific reason to do this? Let me know if it doesn't work as desired and share your improvements. I didn't do proper testing as I don't fully appreciate all corner cases of the use case. On select tag, you can use it if you like how this document works #+SELECT_TAGS: latex * common intro test ** html intro :html: html ** latex :latex: latex * common next section Next section > Just adding "backend" to "select-tags" seems simpler to me, and I > wonder whether "exclude-tags" even behaves correctly for headlines > with more than one tag.

You should be able to test this in a normal org document. –Rasmus -- C is for Cookie
