Useful syntax highlighting (font lock) in a mixed xml lua file

[Timur Aydin <ta@taydin.org>]

Hi,

I am working on an xml file that has an embedded CDATA section which 
contains lua source code. I am mostly working on the lua code and would 
like that code to be syntax highlighted by emacs. When I activate 
lua-mode, it understandably gets confused because of all the surrounding 
xml. When I activate xml-mode, the xml stuff is properly syntax 
highlighted, but the lua code in the CDATA section is uniformly colored 
plain text.

Is there a way to utilize font-lock mode in a sensible manner? I 
attempted to put the lua code in a separate file (script.lua) and then 
included it into the xml using DOCTYPE and ENTITY tags, but this didn't 
help, because I don't have any control over the software that parses 
this xml file. It isn't able to deal with extra xml tags.

So my only hope is to be able to tell emacs to font-lock a region 
bounded by a CDATA tag using lua-mode and to font-lock the rest using 
xml-mode. Is there a way to do this?
