It the same issue as the XML 'attribute or subelement' debate. A sexp could contain everything... it seems to me that the 'rule' was "first element is the record type, following are items containing attributes/subelement"

The issue is when to stop since if you says that instead of

(output (type dxf) (stem "Assembly") ... )

you have to use

(output dxf (stem "Assembly") ... )

then why not

(output dxf "Assembly" ... )

or even a lambda list with keywords (the last one could be a lambda list, too)

(output :type dxf :stem "Assembly" ... )

And you're lucky we don't have destructuring binds in C++ ...

Do we have some design doc explaining the use of sexps in file formats?

At the moment I implemented the output dir feature from the plot dialog. So you get:
- The output directory from the plot dialog
- The base name from the board file
- A stem declared in the plot statement
- An extension which could be the default from the file type or specified with the stem

Should be flexible enough... with some more work we could also set the output dir as a plot-level attribute instead of a job-level one. But then just put the full filename instead of a stem to add to a board name.

I'd leave that for a successive step of refinement, now I'm trying to make the parser work.
