<para>One of the view technologies you can use with the Spring Framework

is Java Server Pages (JSPs). To help you implement views using Java Server Pages

the Spring Framework provides you with some tags for evaluating errors, setting

themes and outputting internationalized messages.</para>

<para>Please note that the various tags generated by this form tag library

are compliant with the <ulink url="http://www.w3.org/TR/xhtml1/">XHTML-1.0-Strict specification</ulink> and attendant <ulink url="http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_XHTML-1.0-Strict">DTD</ulink>.</para>

Fits nicely when used in conjunction with Spring's own validation error

classes which all implement the MessageSourceResolvable interface. For

example, this allows you to iterate over all of the errors in a form,

passing each error (using a runtime expression) as the value of this

'message' attribute, thus effecting the easy display of such error

messages.</para>
