When exporting a subtree, I often use the attach functionality (C-c C-a) to "attach" files to a heading. This gives the heanding an :ATTACH: tag.
When exporting such a subtree via latex to pdf, using org-export-dispatch (C-c e) the output in pdf contains the :ATTTACH: tag. If I use other tags on headings, they are not printed, which is what I expect to happen, given my configuration. Possibly related is that setting '#+EXPORT_EXCLUDE_TAGS: exclude' also does NOT hide the section having that tag if using a #SETUPFILE directive. It *does* work when setting the 'org-export-excluded-tags' variable directly, so I think this is a separate issue. marcel Emacs : GNU Emacs 24.3.4 (x86_64-unknown-linux-gnu, GTK+ Version 3.6.0) of 2013-03-30 on mrb Package: Org-mode version 8.0-pre (release_8.0-pre-11014-gd195e8 @ /home/mrb/dev/emacs/packages/org-mode/lisp/) -- Marcel van der Boom -- http://hsdev.com/mvdb.vcf HS-Development BV -- http://www.hsdev.com We use bitcoin! -- http://bitcoin.org
