The base text direction property is implemented as the
attribute baseTextDirection of the
tag jv:messageBox. For example:
<jv:messageBox id="messageBox" styleClass="message-box" baseTextDirection="LTR"/>
When other JSF components use a messageBox to display text, the messageBox defaults to the same base text direction value as the component,
unless a value of its own is defined.
"LTR": Left to Right text.
"RTL": Right to Left text.
"Contextual": Indicates no predefined direction; the actual direction is determined
by the content.
