<p>Placeholder for form error messages.
This is used on a form to mark where error messages resulting from field or form validation are to be placed.
This will be rendered if the vc_is_valid member of the enclosing page is false.
If rendered, this prints an error message generated by a validator or a catch handler.
This control wiil not be instantiated. The error-summary may show errors for all controls or for a group of controls whose name matches a given regular expression.
The vc_error_message members of all controls whose validation failed will be shown at the place marked by this control if attribute 'match' is not specified. Otherwise the vc_error_message of controls whose validation failed and 'name' matches the pattern specified will be shown.

<div class="formalpara">
<strong>match</strong>
<p>
This attribute specifies a regular expression to be matched against names of controls with failed validation.
The expression may match more than one control name, concatenating the messages in document order of controls. In this way an error summary may appear in
different places of the page to print errors for different controls.

The form contains two v:textarea controls with v:validator elements inside.

so the page is instantiated again.
