RE: [xml-dev] Syntax versus Semantics (was: "vocabulary constraints

[rjelliffe@allette.com.au]

Is it 1998 again?

Computers only operate using symbols, therefore documents only contain
"syntax". The "semantics" is the metamodel behind the surface syntax, and
the alogrithms.

So if you did want a definition of semantics, you might use the idea of
syntax and algorithms that applies to domain-specific metamodels rather
than semantics and syntax that applies either immediate "surface" syntax
(e.g. XPaths) or to generic metamodels (e.g. XSD components.)
