#105 dblatex does not process book containing articles correctly

[Gilles Dartiguelongue]

One of the nice features of docbook is to allow creating a book from a collection of articles.

I wrote a simple example that fails to process because conversion to LaTex creates two documentclass calls which is not supported.

In this specific case, I think articles should be converted to parts or chapters.

Example document attached.
