XML Naming Rules not following standard?

[Suter-IK]

https://www.w3schools.com/xml/xml_elements.asp states the following: XML elements must follow these naming rules:

• Element names are case-sensitive
• Element names must start with a letter or underscore
• **Element names cannot start with the letters xml (or XML, or Xml, etc)**
• Element names can contain letters, digits, hyphens, underscores, and periods
• Element names cannot contain spaces

We have the elements «XmlStandardVersionNo» and «XmlStandardSubset» which do not follow the standard XML rules. How can we fix this? I suggest to replace the elements by «StandardVersionNo» and «StandardSubset» but how can we maintain backwards compatiblity? A feedback from a customer was the following:

Das SAP PO hält sich offensichtlich an diese Konvention und kann nach dem Import der Definition die darin enthaltene Nachricht nicht lesen.

It's a bug and we must fix it, but as this did not seem to create problems in most applications, I suggest not to revise V4.4.0 for this.

Since "Standard" can be ambigous, I will rename to "SdscomVersionNo" and "SdscomSubset".
