<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>

<para>A MessageSourceResolvable argument (direct or through JSP EL).
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>
