i18n:text
element is used to translate any text, with
or without markup. Example:
<i18n:text> This is <strong>translated</strong> string. </i18n:text>
public static final String I18N_TRANSLATE_ELEMENT
i18n:translate
element is used to translate text with
parameter substitution. Example:
<i18n:translate> <i18n:text>This is translated string with {0} param</i18n:text> <i18n:param>1</i18n:param> </i18n:translate>The
i18n:text
fragment can include markup and parameters
at any place. Also do parameters, which can include i18n:text

Constant Field Valuespublic static final String I18N_CHOOSE_ELEMENT
i18n:choose
element is used to translate elements in-place.
The first i18n:when
element matching the current locale
is selected and the others are discarded.
To specify what to do if no locale matched, simply add a node with
locale="*"
. Note that this element must be the last
child of <i18n:choose>.
<i18n:choose> <i18n:when locale="en"> Good Morning </en> <i18n:when locale="fr"> Bonjour </jp> <i18n:when locale="jp"> Aligato? </jp> <i18n:otherwise> Sorry, i don't know how to say hello in your language </jp> <i18n:translate>

elements,
with the exception of other i18n:*
elements.

as
its value to provide multilungual value. Parameters can have
additional attributes to be used for formatting:
type
: can be date, date-time, time,
number, currency, currency-no-unit or percent
.
Used to format params before substitution.value
: the value of the param. If no value is
specified then the text inside of the param element will be used.locale
: used only with number, date, time,
date-time
types and used to override the current locale to
format the given value.src-locale
: used with number, date, time,
date-time
types and specify the locale that should be used to
parse the given value.pattern
: used with number, date, time,
date-time
types and specify the pattern that should be used
to format the given value.src-pattern
