I think STEP (the CAD graphics format) is an exception.

A language called EXPRESS (specified in something like BNF) is used
to specify a "schema", and this specification can then be used to
write parsers for the actual file.  All of this is specified in
standards which are quite expensive.

When I had occasion to write out CAD data from programs I wrote
myself, I looked at this workflow for an hour and decided to use
IGES instead.
