----------------------------
Type-Dependent Parsing

Parsing of values is currently type dependent.  Is that acceptable?

----------------------------
Pros

Makes parsing easier.

Fancy parser tricks.  For example, we know exactly when a value expression ends.  We don't really need delimiters between fields in a record.  The delimiters are only to enforce readability.

----------------------------
Cons

Coupling?

Can't have XML Schema's "xs:any" tag that blindly consumes unknowns.
