reset data src

[pettaa123]

It is possible to assign values to data's attribute expr.
Why is it not possible to manipulate data's attribute src?

It is possible to do with <scxml> attribute 'binding=late'

<scxml binding="late" datamodel="ecmascript" name="ScxmlShape1" version="1.0" xmlns="http://www.w3.org/2005/07/scxml">
	<state id="StateShape1">
		<datamodel>
			<data id="Var1" src="script1.js"/>
		</datamodel>
		<onentry>
			<log expr="Var1" label="Var1"/>
		</onentry>
		<transition event="step" target="StateShape2"/>
	</state>
	<state id="StateShape2">
		<datamodel>
			<data id="Var1" src="script2.js"/>
		</datamodel>
		<onentry>
			<log expr="Var1" label="Var1"/>
		</onentry>
		<transition event="step" target="FinalShape1"/>
	</state>
	<final id="FinalShape1"/>
</scxml>

script1.js

"this is the 1 script"

script2.js

"this is the 2 script"

Output:

[Log] Var1: "this is the 1 script"
[Log] Var1: "this is the 2 script"
