JASPI documentation is not sufficient

Chapter "Configure Java Authentication SPI for Containers (JASPI) Security" need more info.

Please fix following two points:

1) There has to be information about configuration of Valve which enables JASPI authentication. You can use community wiki as a starting point:
https://community.jboss.org/wiki/JBossAS7EnablingJASPIAuthenticationForWebApplications

2) Use CLI commands instead of XML fragments to describe how to configure a security domain with JASPI authentication.
E.g:

/subsystem=security/security-domain=jaspi-test:add(cache-type=default)
/subsystem=security/security-domain=jaspi-test/authentication=jaspi:add
/subsystem=security/security-domain=jaspi-test/authentication=jaspi/auth-module=basic-auth-module:add(code="org.jboss.as.web.security.jaspi.modules.HTTPBasicServerAuthModule", flag="required", login-module-stack-ref="lm-stack")
/subsystem=security/security-domain=jaspi-test/authentication=jaspi/login-module-stack=lm-stack:add
/subsystem=security/security-domain=jaspi-test/authentication=jaspi/login-module-stack=lm-stack/login-module=users:add(code="UsersRoles", flag="required", module-options=[("usersProperties"=>"${jboss.server.config.dir}/jaspi-users.properties"), ("rolesProperties"=>"${jboss.server.config.dir}/jaspi-roles.properties")])
reload
