That can't possibly work -- you _must_ use the right namespace name
for things to be recognised as schemas at all.  If you want to check
against a local copy, use the
{http://www.w3.org/1999/XMLSchema-instance}schemaLocation feature, or
supply the correct local version on the command line, e.g.

python applyschema.py [your schema doc't URL here] [URL of local copy of XMLSchema.xsd here]

xsd:key and friends must appear inside <xsd:element>.  If you want
global scope, put them inside the <xsd:element> which declares the
document element.
