Recently I observed  an even  better  possibility  to have one  hilight-scheme
inside an other. The following will let you have latex-hilighting inside html,
html-hiligthing inside latex, cpp inside html, emf inside Email and so on ....

==== hilight_change.emf start ================================================

define-macro hilight-javascript-inside-html
    ; this macro has to be inside myhtml.emf
    execute-file "hkjava"
    hilight .hilight.html 0x80 "<Script language=\"JavaScript\">" .hilight.java $global-scheme
    hilight .hilight.java 0x80 "</Script>" .hilight.html $global-scheme
    screen-update
!emacro

define-macro hilight-latex-inside-html ; macro in myhtml.emf
    ; using the <pre> tags for input of code
    execute-file "hklatex"
    hilight .hilight.html 0x80 "<pre>" .hilight.latex $global-scheme
    execute-file "hklatex"
    hilight .hilight.latex 0x80 "</pre>" .hilight.html $global-scheme
    screen-update
!emacro

define-macro hilight-html-inside-latex ; macro in mylatex.emf
    ; using the \verbatim-environment for input of code
    execute-file "hkhtml"
    hilight .hilight.latex 0x80 "\\begin{verbatim}" .hilight.html $global-scheme
    execute-file "hklatex"
    hilight .hilight.html 0x80 "\\end{verbatim}" .hilight.latex $global-scheme
    screen-update
!emacro

==== hilight_change.emf end ==================================================
