Commands need to be unexpandable because when you use the “command”.

This is necessary because I check for a command and this needs \unexpanded\def to work.

You can create a unexpandable command with \starttexdefintion by adding
the unexpanded keyword as first argument to the environment.

\starttexdefinition unexpanded cmd #first #second
 \placeannotationcontent
\stoptexdefinition
