Dear Filip,

I am working in automated reasoning myself and have worked on such 
matters. The first question you want to pose yourself is whether you 
want to generate presentation MathML (this is what can be directly 
displayed in a browser) or content MathML (better, if you want to be 
able to read the back into a machine and communicate it to other 
machines). Of course content MathML can be converted to presentation 
MathML by standard means (style sheets).

That leaves the question about the markup of AR structures as you have 
tried with your tags. There is already the OMDoc format 
[http://www.mathweb.org/omdoc] that does the same thing and may be 
suitable for your task. Using OMDoc may make your system interoperable 
to others that already use the format.

Maybe you can tell us more about your system.

Michael
