Also in the model itself:

{code}
    static final SimpleAttributeDefinition OWNERS = new SimpleAttributeDefinitionBuilder(ModelKeys.OWNERS, ModelType.INT, true)
            .setXmlName(Attribute.OWNERS.getLocalName())
            .setAllowExpression(true)
            .setFlags(AttributeAccess.Flag.RESTART_ALL_SERVICES)
            .setDefaultValue(new ModelNode().set(2))
            .setValidator(new IntRangeValidator(1, true, true))
            .build()
    ;
{code}

We explicitly specify the value (4) so we don't rely on a default, thus the transformer is *not needed*.

> WildFly uses DIST by default using 4 owners, which is too conservative.  I think we should lower this default value to 2, which is Infinispan's default value.  We'll get a nice performance bump too.
> Don't forget to create transformers to handle the default value change for old model versions.
