Controlling the Name Comparison of Literal XML Elements 
During the deserialization of literal XML elements, you can use the optional attribute tt:lax to control whether the name of an element is taken into consideration. After tt:lax, you can enter the following values for lax_flag:
... ″on″|″off″|″deep-on″|″deep-off″ ...
If you specify tt:lax with the value ″off″, the XML inbound stream must contain an element of the same name with all literal attributes attr of the same content. If you specify tt:lax with the value ″on″, the element in the XML inbound stream can have any name, but the expected attributes must still match. You use the values ″deep-on″ and ″deep-off″ for tt:lax to set the setting ″on″ and ″off″ for all subelements of the current element; however, they can be overwritten locally there. If you do not specify tt:lax, the setting complies with the surrounding context. By default, ″deep-off″ is set for a template.
We have the following XML fragment:
<X my_attr="attr">abc</X>
Due to tt:lax=″on″, the ST program below can still deserialize this fragment despite differing element names:
Syntax
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="ROOT"/>
<tt:template>
<Y tt:lax="on">
<tt:value ref="ROOT"/>
</Y>
</tt:template>
</tt:transform>
