Can you do that with the SDK?

I have a question concerning the SDK. In a project, we want to automate some Editing-Functions and the "Premiere_SDK_Guide.pdf" leaves some questions:

1) Is it possible to write a plugin, that read pathes from ressources (for example Images and Audio from an XML-file) and put these at specific places on the timeline?

2) With video- and audio-transitions?

Even if the above is not possible, than can you automatically:

3) Set Chapter-Markers?

4) Export to Encore or directly as a DVD?

Thanks in advance,

Hans
