in strc-ren you can see exmaples of definitions; you can either define a 
macro and hook it in (old method) or use setups in which case you have 
access to more properties

commands like \veryraggedright are low level (often fast) variants of in 
this case \setupalign[middle,broad] (just use \setupalign if more 
advanced control is needed)

\defineheadalternative
   [mymiddle]
   [alternative=horizontal,
    renderingsetup=head:mymiddle]

\startsetups[head:mymiddle]
     \ruledvbox {
         \headsetupspacing
         \veryraggedcenter
         \begstrut
         \ifconditional\headshownumber
             \headnumbercontent
             \quad
         \fi
         \headtextcontent
         \endstrut
     }
\stopsetups

the struts enforce consistent spacing
