DITA has semantics for the more general "multistep processes" via the 
"task" topic.  If you have a nice, self-contained derivation, this would 
be an appropriate vehicle to express it.  (e.g., the "derivation" topic 
could be a specialization of "task").  It does not have 
out-of-the-box-support for Openmath, but it is designed to be extended. 
Adding the <OMA> element as a child of 
<taskbody><steps><step><cmd>...</></></></> should do the trick.  (extend 
their <foreign/> element.)  You will, of course, have to adapt the 
processing s/w to handle the new tags.
