 ### Enforcement for scripts ### {#enforcement-in-scripts}
 
+This document modifies how {{HTMLScriptElement}} [=child text content=] can be set to allow applications to control dynamically created scripts. It does so by
+adding the {{HTMLElement/innerText}} and {{Node/textContent}} attributes directly on {{HTMLScriptElement}}. The behavior of the attributes remains the same
+as in their original counterparts, apart from the additional behavior of calling [$Get Trusted Type compliant string$].
+
+Note: Using these IDL attributes is the recommended way of dynamically setting the URL or a text of a script. Manipulating attribute nodes or text nodes directly will call a default policy on the final value when the script is prepared.

 #### Slots with trusted values #### {#slots-with-trusted-values}
 
 This document modifies {{HTMLScriptElement}}s. Each script has:
 
 : an associated string <dfn export for="HTMLScriptElement">script text</dfn>.
 ::  A string, containing the body of the script to execute that was set
-    through a {{StringContext}} compliant sink. Equivalent to script's
+    through a compliant sink. Equivalent to script's
     [=child text content=]. Initially an empty string.

-This document modifies how {{HTMLScriptElement}} [=child text content=] can be set to allow applications to control dynamically created scripts. It does so by
-adding the {{HTMLElement/innerText}} and {{Node/textContent}} attributes directly on {{HTMLScriptElement}}. The behavior of the attributes remains the same
-as in their original counterparts, apart from additional behavior triggered by the {{StringContext}} extended attribute presence.
+The {{HTMLScriptElement/innerText}} setter steps are:
 
-Note: Using these IDL attributes is the recommended way of dynamically setting URL or a text of a script. Manipulating attribute nodes or text nodes directly will call a default policy on the final value when the script is prepared.
+1.  Let |value| be the result of calling [$Get Trusted Type compliant string$] with

+#### The {{HTMLScriptElement/textContent}} IDL attribute #### {#the-textContent-idl-attribute}
+
+The {{HTMLScriptElement/textContent}} setter steps are to, if the given value is null, act as if it was the

+
+1.  Let |value| be the result of calling [$Get Trusted Type compliant string$] with
+    {{TrustedScript}}, [=this=]'s [=relevant global object=], the given value, `HTMLScriptElement textContent`, and

+1.  [=String replace all=] with the given value within [=this=].

+#### The {{HTMLScriptElement/src}} IDL attribute #### {#the-src-idl-attribute}
 
-On setting the {{HTMLElement/innerText}}, {{Node/textContent}} and {{HTMLScriptElement/text}} IDL attributes execute the following algorithm:
+The {{HTMLScriptElement/src}} setter steps are:
 
-1. Set [=script text=] value to the stringified attribute value.
-1. Perform the usual attribute setter steps.
+1.  <ins>Let |value| be the result of calling [$Get Trusted Type compliant string$] with
