For instance how can <csymbol> be intended to denote symbols with an
_external_ definition if the definition location doesn't matter at the
same time.

I am just curious, what is the difference between



<ci definitionURL="http://www.w3.org/TR/MathML2/appendixc.html#cedef.sin

What about next?

<apply><ci>diff</ci> arguments</apply>

<apply><csymbol>diff</csymbol> arguments</apply>

<apply><diff/> arguments</apply>
