ST - tt:lax , Name Comparison of Literal XML Elements

Syntax
... tt:lax="on"|"off"|"deep-on"|"deep-off" ...

Effect
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.

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, a template has the setting
"deep-off" .

Example
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:
<(><<)>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
