XML, putting syntax

[nebulom]

I want to put syntax on an xml document. Something like should start with <class> element and under class element, only <attribute> element is allowed. On class element, name and type and modifier attributes only are allowed.

Can I do this? If so, please provide some links. Thanks. Btw, I need my document to return an error if, let's say, I put <qwerty> under class element.

Again, thanks.
