Ein hoffentlich sinnvolles Snippet...

Hiermit kann man an RTE / CK Editor Download Tags Informationen zum Download automatisch an das Link Tag  (title="...", downlaod="...") und den Link Text (Dateiendung, Dateigröße) anhängen.

So sieht dann ein Download Link (hip, 130KB) aus, File Extension und Size am Text, sowie Title und Download Attribute am A-Tag.
Im Backend wurde nur die Datei verlinkt, also dort "De(r)faul(t)e Redakteur" Eingabe, nix "Sie müssen erst den Nippel durch die Lasche ziehn" ;-)

<a class="link_internal_download" href="t3://file?uid=113">Download Link</a>

Hier das Typoscript Snippet, sollte so auch mehrsprachig funktionieren.
