You can manage conditionals by using expressions and fieldexpressions , so
your validation below would become :
<field name="myInputFieldName">
<field-validator type="fieldexpression">
(#params['myInputFieldName'] neq null) && ( myInputFieldName
neq null & myInputFieldName.trim().length() gt 0 )
<message key="errors.required"/>
</field-validator>
</field>
