External DTD & namespaces

[Andrew Layman]

DTDs and namespaces are not fully integrated yet.  You can easily use
namespace prefixes in your DTDs, much as you show, but you must then be
careful that your instances use exactly the same namespace prefix.  

Hopefully, future work on XML schemas will give you the ability to declare
namespaces in schemas (DTD being a type of schema) and then you can validate
based on the URI the prefix stands for, not just the literal characters of
the prefix.  We are not there yet.

Hello All!

Dummy question:

I want to use namespace prefixes in element declarations of the
external/internal DTDs.
For example, I want to define namespace "myns" and use with each DTD
declaration:

<!ELEMENT myns:point (int, int)>

Where I should put "myns" namespace declaration?

Thank you in advance,

All the Best!
