Ok. Have tried it. It seems to work on line 2. Where can I find documentation about these ctx files? Denis Maier schrieb am Do., 16. Mai 2019, 12:27:

<?context-directive job ctxfile somefile.ctx?>

Just after the xml declaration? Like on line 2?

...

with "somefile.ctx" being:

<?xml version='1.0' standalone='yes'?>

ctx:job ctx:messageMy very special style ctx:process ctx:flags <!-- ctx:flag>purge</ctx:flag --> ctx:resources ctx:environmentwhatever.tex
