should a conformant parser reject symbols containing more than one slash?

If not, then which slash marks the division between prefix and base name?

From the sentence fragment, "...once only in the middle of a symbol," I would take a/b/c to be invalid edn since one of two things should have happened to allow that to be valid. Either, remove the extra slash and separate the a from b/c with whitespace, or, remove the extra slash and separate the a/b from c with whitespace.

I don't think there is any ambiguity in the current casual spec about how many / characters may appear in a valid Symbol.

Yea, you're right. My parser rejects symbols with more than one slash, but somehow, I forgot about that sentence in the spec.
