<p class="MsoNormal">1. Following some initial testing, am happy to report that this approach to embed source code in Script nodes seems consistently feasible for X3DUOM, Python, Java and X3D Ontology all at once.<br>
<br>
It will take a little work to fully implement, but it should improve the expressive power (meaning "fix a hole") in each of our programming-language bindings.<br>
<br>
------<br>
<br>
2. In some sense embedding script code is already possible - you can put such a program in first string contained in a Script url list - but in practice that tends to be quite difficult because then all sorts of obfuscating escaping of special characters has
to take place.<br>
<br>
So having a separate place for source-code blocks is very helpful. The X3D Architecture recognizes this possibility and defines corresponding behaviors. Further details can be found in X3D XML Encoding.<br>
<br>
* X3D4 Architecture, clause 19 Scripting component, 29.4.1 Script<br>
* <a href="https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1/Part01/components/scripting.html#Script" target="_blank">

<br>
* X3D4 Architecture, 9.2.3 Scripting language protocols<br>
<a href="https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1/Part01/components/networking.html#ScriptingLanguageProtocols" target="_blank">https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1/Part01/components/networking.html#ScriptingLanguageProtocols</a><br>
<br>
* X3D XML Encoding, Clause 4 Concepts, 4.3.13 Encapsulating Script node code<br>
<a href="https://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#EncapsulatingScriptNodeCode" target="_blank">https://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/concepts.html#EncapsulatingScriptNodeCode</a><br>
<br>
"If both a url field and a CDATA clause are encountered, the url field is processed first. Thus, the CDATA construct can also be considered equivalent to one additional value appended to the url MFString array. This ordering allows an online script code
url to take priority over fallback default script code in the CDATA construct. This ordering also allows run-time updates if a viewer is connected to the network, if so desired by the originating author."<br>
<br>
------<br>
<br>
3. Next - naming. "CDATA" is pretty obscure as a field name, especially since that is an XML datatype (for Character Data). Thus am thinking "sourceCode" might be a better name... what do you think?<br>
<br>
The ability to embed safe scripting code within any X3D Script is a powerful capability that also improves security possibilities for advanced X3D... it is easier to secure and safely transport an embedded script than it is to have multiple files handled safely.<br>
<br>
John, it looks like we already did something just like this in the JSON encoding, we called it "sourceText", excerpt follows. (Excessive string quoting was necessary to pass JSON parsing rules for multiline text.)<br>

XMLSpy was stricter about type handling than our Java-based Saxon10 conversions for this example. XMLSpy diagnosed some problems that I fixed.<br>
<br>
After also fixing the stylesheet name provided by a diagnostic, all X3dToPython.xslt changes were checked into subversion.<br>

So, embedded CDATA scripting code inside a Script node (and similar Shader nodes) remains an omission in our Python support.<br>
<br>
To remedy this, we need to create a special field in the X3DPSAIL class Script. *What shall we call it?* Creating a Script member named CDATA seems unambiguous and eponymous with the XML encoding...<br>
