That's behavioral semantics (what to do), not document semantics (what is meant). It is impossible to define document semantics without reference to the recipient: indeed, as a member of the pragmaticist tradition I define the semantics of a document as its effect on the recipient. A book written in Georgian has no semantics to me, for I cannot understand a single word of it. > What I have found is that making use of syntax to encode semantics is > always a mistake. See, if I didn't know that you were talking about behavioral semantics, that would be incomprehensible. This very email uses syntax (English syntax) to encode the semantics of what I am (I hope) communicating to you. Indeed, there is no other way for me to communicate it. > Using different tags for "DateTime" (=String) and "DeltaTime" > (=Integer) avoids that whole business.

I'll use a computer.
