To find the schema applicable for a namespace, we should not have
a function:

Instead, there it should go through some service:
    get-resource(namespace-URI, namespace-resolver-service-URI,
        preferred-syntax, resource-type)
where resource-type could be "syntactic-schema", "semantic-schema",
"documentation", etc.
