Dtd and Schema reference 1

[papaya81]

Hi,
I have a doubt concerning the correspondance between reference to a Dtd and to an XML Schema. In the doctype declaration you can use the keyword SYSTEM or PUBLIC. How is this handled in the Schema?Is the following correspondance true:

SYSTEM --> xsi:noNamespaceSchemaLocation
PUBLIC --> xsi:schemaLocation

Or the 2 xsi depend only on the existence of the target namespace?

Thanks for help

>PUBLIC --> xsi:schemaLocation
This correspondance is of no meaning. It is a wrong line of reasoning. There is no truth in it, so don't mislead yourself.

>Or the 2 xsi depend only on the existence of the target namespace?
That's about right. If there is any nuance to make, it does not come up to my mind rightaway.

Thank you for this answer. But how do you handle PUBLIC and SYSTEM keyword in Schemas?

One does not need to handle it in any special way. If the schema documents are located in a publicly accessible url, it would be about PUBLIC. If the schemas are located in your local file system or private network, it would be about SYSTEM.

But, in any case, the value of those attributes are _not_ the ultimate decree. They are only suggestive. They can be override by the application.
