Chicken or Egg, XML or XSD

[Ralph Krausse]

What comes first, XML or XSD? When you start building a project that
will include XML, what would you start on first, building your XML data
file or your XSD schema file?

A schema is used to validate an XML instance. It defines the nature and
constraints on the data in an XML file.

Both. Sometimes one is imposed before the other, but as a general
"clean slate" approach, you iterate between the two of them.

Also in practice, people normally have XML and DTD data from previous
projects that naturally upgrade to using XSD and newer parsing technologies
etc..
