Wow, This is a nice piece of work. I've yet to look at the code, because I'm too lazy to download the .tgz and unpack it - could you add highlighted source to the docs?
I love the idea of the generator, the XML syntax seems very neat and capable to describe a lot of things. And even the generated PHP Code seems reasonable :)
If this package comes with as many default highlighters as Text_Highlight - I am more than happy to see this succeed over that package. I would like to work with you to make sure that all the functionality I wanted in Text_Highlight is still there (i.e. static calling of each highlighter)
I will re-generate the docs with source code and upload it now. Adding more highlighters is just a matter of time, and it is actually easy.
