default value in infinispan subsystem schema is ignored

Because of the way the infinispan subsystem is parsed:
https://github.com/jbossas/jboss-as/blob/master/clustering/infinispan/src/main/java/org/jboss/as/clustering/infinispan/subsystem/InfinispanSubsystemXMLReader_1_1.java#L297

The default value for l1-lifespan attribute specified here:
https://github.com/jbossas/jboss-as/blob/master/build/src/main/resources/docs/schema/jboss-as-infinispan_1_1.xsd#L400

is ignored.
Could we changed it to zero in the schema, so that there aren't doubts whether L1 is or is not enabled by default when this attribute is omitted ?

Correct behaviour IMO should be: L1 is disabled by default.
And that is the way it is, this default value just adds to confusion.
