Hey there,

I am having trouble understanding some basic blank page behavior. I hope that somebody of you can point me in the right direction.

My primary goal is to create application documents consisting of various .tex components and with external PDF pages inserted as well. The second part of that goal is to use multiple-level bookmarking as well. Bookmarking should look like this:

- Letter
- Resume
- Testimonies
-- Testimony A
-- Testimony B
-- Testimony C

In the following MWE you can see my progress along with some notes to help understanding. 

There are two questions, I'd wish could be answered:

1. Why does TeX insert a blank page before a pagefigure I enclose within a (hidden) head?

2. Can the \bookmark[list]{text} command be somehow used for multi-level bookmarking?

While the first question would make up for a more consistent solution, the second question would do the job as well.

I hope some of you can enlighten me. 

Cheers, k
