The base text direction property is implemented as the
attribute baseTextDirection of the
tag jvf:tooltipInteractor. For example:
<jvf:tooltipInteractor id="tooltipInteractor" baseTextDirection="Contextual"/>
"LTR": Left to Right text.
"RTL": Right to Left text.
"Contextual": the default value, which indicates no predefined direction; the
actual direction is determined by the content.
The following limitation exists: if a template is used,
contextual direction is not supported. See Using the tooltip template.
