Correct filename of example

[tschmidtb51]

The example has an invalid filename according to section 5.1. Either, we change the /document/tracking/id or we change the filename. Given that we might want to add multiple files to enhance the coverage, I guess it makes sense to update the /document/tracking/id, e.g. to example 01 valid and the filename to example_01_valid.json.

@santosomar, @sthagen: Thoughts?

I like the latter (update the /document/tracking/id, e.g. to example 01 valid and the filename to example_01_valid.json)
