I don't suppose there is a universal schema language available for S
expressions, nor do I suppose many people want such a thing. You specify
S expression encoding the way you specify Python library functions.

I think the worst part of XML is that you can't parse it without a DTD
or schema.

I was very hopeful about json until I discovered they require the parser
to dynamically support five different character encodings.

XML at least standardized on UTF-8.

I have found ast.literal_eval() to be highly usable.

Pickle I would advise you to stay away from: <URL:
