-ConTeXt has a nice structure in order to define new math commands in which some characters are stacked over another one.
-A typical example is when you want to put a small circle on top of a letter (as one would when defining the topological interior of a set…).
-To do so we define first a new stacker named here {{code|l=MySymbol}}, and then invoking that we define two new commands {{code|l=\interior}} and {{code|l=\starred}}

-	[voffset=-.3\mathexheight,
-	hoffset=\zeropoint,
-	mathclass=ord,
-	topoffset=.4\mathemwidth, % poor man's italic correction
-	middlecommand=\mathematics]

-%Here is the new command \type{\interiorset{K}}: $\mathring{K} \neq \interiorset{K}$
-Here is the new command \type{\interior{K}}: $\interior{K}$. Compare this to \type{\mathring{K}}: $\mathring{K}$.
-Here is the new command \type{\starred{K}}: $\starred{K}$
