--- Comment #1 from Tomás Cohen Arazi <tomascohen at gmail.com> ---
I've been briefly poking at this. My findings are that the resumption token
itself doesn't need to have a specific structure and is up to the
implementation to defined how that token should look like.

Koha uses this structure:

"$metadata_prefix/$cursor/$from/$until/$set/$deleted/0/$next_id"

This is an extreme reasoning, but things can be underspecified so they fallback
to some default. I'm not sure if 'junk' couldn't be some valid resumption token
if we decided to encode/compress the resumption token...

That is, somehow, a weakness on the validation tool. They picked 'junk' meaning
'some random word'.

That said, though: we know the structure of our resumption tokens (as pasted
above) and we could be returning 'badResumptionToken' when the request doesn't
comform to that structure.

Do we agree?
