public class TransformTag extends HtmlEscapingAwareTag
spring:bind
tag (or a data-bound
form element tag from Spring's form tag library).
The BindTag has a PropertyEditor that it uses to transform properties of a bean to a String, useable in HTML forms. This tag uses that PropertyEditor to transform objects passed into this tag.

public void setValue(Object value)
The value can either be a plain value to transform (a hard-coded String value in a JSP or a JSP expression), or a JSP EL expression to be evaluated (transforming the result of the expression).
Like all of Spring's JSP tags, this tag is capable of parsing EL expressions itself, on any JSP version. Note, however, that EL expressions in a JSP 2.0 page will be evaluated by the JSP container, with the result getting passed in here. For this reason, the type of this property is Object (accepting any result object from a pre-evaluated expression) rather than String.
