There's another school which holds that "syntax IS semantics". A DTD for X.509 certificates allows me to express what parts of the certificate I consider required, what parts of the certificate I consider optional, as well as the legal forms of the parts themselves. I can tell whether or not a certificate is valid, and also *why* (e.g. no signature algorithm name was provided, the "not after" date was malformed). I think that if I can answer "why" questions, I'm operating in the semantic realm. Meaning may only be conveyed (manifested?) in "running code or human-readable prose", but the meaning is latent in the syntax, and couldn't be conveyed if it wasn't already there.
