Just noticed this (and it's something of a judgment call): the "caption" and "description" tags are reversed from the intended usage—or at least from the usage in the example .pbg files.
The more verbose ("Parts in…") tag should go under description, which appears in the hint bar of the main editing window.
The less verbose tag should be the caption, which appears in the top of the part bin itself. It's meant to be as short as possible since the part bin window is typically not very wide.
Although this is made somewhat moot by the way the generator is set up, since it adds the set name, so you wouldn't want to reverse it completely. Still, I think the expected output should be something like this, to match the "official" example files:
