<concatAttribute target="targetname" name="regexp" 
                 value="attributelist" separator="separatorstring" 
                 [maxLengt="maxlength" 
                 defaultValueForNotExistent="attributelist"] 
/>
Description Specifies an attribute value created from values of the attributes in the attributeList separated by the given separator. Each attribute has to be surrounded by a single quote ('). If maximum length is efined, the value will be cropped to the maxLength. If an attribute from the list does not exist, the defaultValueForNotExistent will be used. If the defaultValueForNotExistent is not defined, the not found attribute will be ignored (also the separator will be not added).
