CLI guide: Add description of [] brackets to chapter "3.8. Add a Value with Special Characters"
If user wants to use [ or ] in String values, he needs to use quotation marks:
[standalone@localhost:9990 /] /system-property=aaa:add(value=[])
{
"outcome" => "failed",
"failure-description" => "WFLYCTL0097: Wrong type for 'value'. Expected [EXPRESSION, STRING] but was LIST",
"rolled-back" => true
}
[standalone@localhost:9990 /] /system-property=aaa:add(value="[]")
{"outcome" => "success"}
[standalone@localhost:9990 /]
