I updated this library from beta/0.9 to 1.0 over the weekend:

[https://docs.racket-lang.org/splitflap/index.html](https://docs.racket-lang.org/splitflap/index.html)

I incorporated a lot of changes based on feedback from folks in [the original Google groups announcement](https://groups.google.com/g/racket-users/c/jpCOkZDtZ_k) and elsewhere:

- Add support for XSLT stylesheets
- Remove `web-server` dependency and build MIME types table directly from source
- Use `delay/sync` for promises to keep them thread-safe
- Fixed and generalized HTML entity encoding (thanks @LiberalArtist for helping with this!)
- Ensure strings that go inside `CDATA` have the magic closing string `"]]>"` escaped
- Accept `any/c` for boolean arguments
- Moved _almost_ all contract boundaries out from functions to module edges
  - (I’m still not sure whether to attempt this for generic functions like `express-xml` where the contracts differ depending on the struct type)
