Thanks Alan for the suggestion, I’ll try it. Doing more research I figured out that \definefont defined such simple command at the expense of eventually repeating the font name and features. 


\definefont[SmallFont][name:EBGaramond*base,xxicentury at \SmallFontSize]  % \SmallFont works


I was also a bit surprised with \tf<size> behaviour when used inside a scope of another one leading to 2 different sizes in output, as in


{\tfd Foo {\tfx Bar1}} {\tfx Bar2} Baz.


For the sake of knowledge I would be interested in knowing if this is expected eventually. 


Thanks a lot


Joseph

Perhaps (untested):

\definealternativestyle [BigFont] [{\setbodyfont [12pt]}]
\definealternativestyle [SmallFont] [{\setbodyfont [8pt]}]
\definehighlight [BigSize] [style=BigFont]
\definehighlight [SmallSize] [style=SmallFont]

\BigSize{Foo \SmallSize{Bar1}} \SmallSize{Bar2} Baz.
