Right, if I validate a document with the Schema. But if I don't want to 
validate a document, but only validate the Schema? Like this? :

xmllint --noout --schema file.xsd

(Note the absence of a xml document)

No, it doesn't work, but it gets my point through.

This one:
http://www.w3.org/2001/XMLSchema.xsd

With the output:

bash-2.05b$ xmllint --schema /tmp/XMLSchema.xsd Severities.xsd --noout

I'm upgrading to 2.6.16.
