Server validation of pattern on WMultiTextField

If a pattern is applied and not matched the error appears twice: first within the last list item and then within the fieldset.

Note this does not happen with mandatory WMultiTextField or with pattern on WTextField.

XSLT error found in wc.ui.multitextfield.xsl line 68.

Checked other similar structured XSLT and this one appears to be the only one with this issue.
