Subject: [PATCH] Fix invalid xs:import of fmi3Annotation.xsd

Neither this schema nor fmi3Annotation.xsd declares a targetNamespace,
so both are in "no namespace". xs:import is for pulling in components
from a different namespace than the importing schema; merging
components from a schema with the same (or absent) target namespace
is what xs:include is for. Using xs:import without a namespace
attribute here is not spec-conformant, and rejected outright by
strict validators (e.g. the Python xmlschema library), even though
lenient ones (libxml2/xmllint) tolerate it.

Closes #7
