Hi,
Right now, we define the level of validity of a documents with
regards to its DTD. For example, the Markup validator validates
document against the DTD.
With the coming of new technologies, often a schema AND a DTD are developed.
The Schema being often more refined, more detailed than the DTD.
For validity:
How do we define the validity of a document
when a schema and a DTD for the same technology
do not express the same constraints?
For Conformance:
How do we explicit the rules for conformance?
When the values are defined in the spec, for example, their type, one
can say that "the value MUST be..." because of the impossibility of
the DTD to express the type of these values, One can say, the
constraints on this attribute is defined by the Schema and you have a
rule at the beginning which says "To conform, the [class_of_product]
MUST respect the Schema..."
