In your standalone.xml file you will find:
<deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"/>
The "urn:jboss:domain:deployment-scanner:1.1" namespace declaration corresponds to the namespace declaration in jboss-as-deployment-scanner_1_1.xsd.
So, jboss-as-deployment-scanner_1_1.xsd describes the schema for that subsystem fragment.
Not sure on the details but if you look at the logging subsystem you'll see
which corresponds to jboss-as-logging_1_1.xsd
Heh, looks like I checked for details too long, question already answered ;-)
