This doesn't actually happen if you run rst2pdf through Sphinx.

You will get warnings like

[WARNING] styles.py:548 Using undefined style 'function', aliased to style 'normal'.
[WARNING] styles.py:548 Using undefined style 'type', aliased to style 'normal'.

but it's a matter of defining a custom rst2pdf stylesheet. It's json
with a sort of inheritance model, so it should be easy to just extend
the existing stylesheet.
