For a number type, the format specification can be currency, percent, integer, or
the type of customized pattern described for <fmt:formatNumber>.
<fmt:parseDate>



The <fmt:parseDate> action parses a date and time value formatted according to locale-
specific rules. A custom pattern can be specified, or locale-dependent default patterns for one
or both of the date portion and the time portion can be selected.
The locale used is the one explicitly specified or is taken from the locale configuration setting
or the locale from the localization context setting. If none of these are set, the locale is
determined as the best match for the user preferences (Accept-Language request header).

<fmt:parseNumber>

The <fmt:parseNumber> action parses a number formatted according to locale-specific
