The idea I have in mind is mostly what James said in a different thread,

CDDefinition/description gives a short and concise description of the symbol in 
plain text

CDDefinition/discussion? gives all the necessary mathematical fine print 
possibly using MathML or even OpenMath for that.


We sant to use the <description> to generate text into the MathML3 
recommendation and for things like tooltips in applications. There we need 
limited length and plain unicode. The <discussion> element is intended for 
implementors (to establish interoperability) and for interested parties who 
look up the CD (beyond a simple tool-tip) and want to understand what is really 
meant. In the <discussion> element I imagine details like the branchcuts to be 
discussed.

That is one of the curent problems, we have not moved the text around,
but that is next. In a way still waiting for David's restructuring of
the MathML3 text generation script to get a better model of what to write.
