The mod_commands wiki page shows a slightly different syntax:

<action application="set" data="api_result=${sched_api(+5 none avmd
${uuid} start)}"/>

Are the brackets optional?

And also, a command like "uuid_setvar" probably does not generate any
value if it is evaluated like an expression.  Which value would be
assigned to the channel variable in such case?

Thanks again.
