-------------------------------------------------------------------

The xsd defaults have no effect on processing; they are there for documentation purposes only (according to Brian).

All default values are controlled through AttributeDefintions within the subsystem definition. This is primarily because management operations, whether they are specified via XML elements or the management interface, all end up as invoked management operations which access the AttributeDefinitions and their defaults. 

The xsd defaults were set up to match the defaults used in the attribute definitions. In the case of l1-lifespan, the default is actually 600000.

When building the Infinispan configuration from the management model information, if l1-lifespan > 0, l1 caching is turned on. So l1 caching is actually on by default (or at least should be by intention).

> 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.
