Some times I think schemas v. DTD's is like religion  !

>Schemas are considerably more flexible in describing data

no doubt about that

>and are more
intuitive

I guess it depends on what religon you were brought up in :>)

>They use EBNF (Extended Backus Naur Form) which is difficult understand

I _love_ EBNF!! It's simple, descriptive and has withstood the test of time,
and does in a couple of lines what other descriptive languages take pages to
do!!

>No support for namespaces, datatypes, and inheritance

>No support for namespaces
There is no doubt that if namespaces are important to you schemas are the
way to go

>datatypes

If you need to store datatypes use schemas, although 98% of the time you
will find a RADBMS is more effective

>and inheritance

well yes, but don't confuse this with extensibility, well designed DTD's
(e.g. docbook) are very extensible

However I will continue to use DTD's for all my document validation and
publishing needs. I for one find them far more intuitive and descriptive
than schemas.

////////////////////////////////////////////////////////////////////////

In defense of Cheryl...

Schemas are considerably more flexible in describing data and are more
intuitive.

Some downsides of DTDs are:

They use EBNF (Extended Backus Naur Form) which is difficult understand
and not XML syntax which requires a separate parser.

No support for namespaces, datatypes, and inheritance.

Benefits of Schemas

Users do not have to learn new proprietary syntax,

The schema language can be readily applicable to existing XML
applications (e.g., editor, browser)

The schema file can be stored in a XML storage system along with XML
documents

The schema language is extensible.

All the schema languages except DTD are written in XML syntax

////////////////////////////////////////////////////////////////////////
////

I will stop there.  That is a very short list of why Schemas are better
choice for the future.

Regards,

Jeff Langdon

Although with Schemas, can't you be more detailed than with dtd's. And
also
manipulate the data with For Each, etc, and also convert it to HTML?
