I know DTD (Document Type Definition) is supported by
Netscape/Firefox and IE.
What exactly do you think Netscape/Firefox support about DTDs? They use
the expat parser and that is not a validating parser so unless you have
an internal subset of a DTD the parser in Netscape/Firefox does not see
the DTD at all.
IE uses MSXML which can validate against a DTD but I think when IE loads
an XML document directly into a browser window then it does not validate.
But I typed some examples from
http://www.w3schools.com/schema/default.asp
Seems no effect on those browsers.
The XML parser in Netscape/Firefox is not a validating parser at all so
I am not sure what effect you are looking for.
MSXML 3 which comes with IE 6 is a validating parser that can validate
against DTDs but to do that you need to apply script.
MSXML 4 can do schema validation but it is not installed by IE so you
need to download that separately and then you can use script inside of
IE to do schema validation if needed.
