Elisha, thanks for the explanation. The difference is clear to me now.

If I understand it correctly, the regular expression in spec JSON is for
information only. It is never compiled into a `re` object.

The actual values are generated in `static_info_parsers` from the
`mapping`. The regular expression is neither used as a value template nor
for value validation.

Is that right?
