Log:
<action dev="CH" type="add">
Simple Formvalidation: FormValidatorAction sets attribute "*" to indicate
overall validation status. Added SimpleFormTransformer that fills XHTML form
fields with values from request parameters and allows conditional error tags
depending on validation result. This removes the requirement for
XSP. Changed ordering of error levels: "notpresent" (indicates that no
validation result is present for this parameter) moves between "ok" and
"error". New error level "maxerror" used in conjunction with the
transformer, is never set, used as upper bound.
