Need to spec the following which coincides with
eclipse-ee4j/mojarra#1092

For a message tag, if there is a user specified "id" value, and there are no
messages to output, then output an empty <span> tag, containing only that 'id'
attribute.

For a messages tag, if there is a user specified "id" value, output an empty
<div> tag, containing only that 'id' attribute if both of the following
conditions are true:

• there are no messages to output
• the messages block is not the special case of messages for development stage
