Ok, how about this example then:

\version "2.14.2"

#(define-markup-command (jcRaise layout props jcText) (markup?)
    (interpret-markup layout props
      (markup #:raise 1.5 #:smaller #:smaller #:smaller jcText )
    )
  )

  #(define-markup-command (jcStack layout props jcHi jcLo) (markup? 
markup?)
    (interpret-markup layout props
    #{ \markup{ $jcHi $jcLo } #}
    )
  )


\relative c'' {
        
        % fine:
        c1-\markup{\jcRaise "XXX"}

        % those two don't work:
        c1-\markup{ \jcStack{"x"}{"y"} }
        c1-\markup{ \jcStack "x" "y" }
}

The definition of \jcRaise works fine. Of course, the definition of 
\jcStack will be different later, for now, I'd just like it to work in 
this simple example.
Sorry for the confusion ...
