Incorrect XML Structure When Converting Record with Type Inclusion to XML

[AzeemMuzammil]

Description: When converting a record object to XML, attributes from included types are incorrectly treated as nested elements rather than attributes. This issue occurs specifically when the record uses type inclusion to inherit attributes, which should be rendered as XML attributes, not child elements. Below are the examples demonstrating the expected and the actual XML output for clarity:

type Child record {
    string childField;
    @xmldata:Attribute
    string childAttr?;
    *Parent;
};

type Parent record {
    @xmldata:Attribute
    string parentAttr?;
};

Generated

<Child childAttr="ChildAttr">
    <childField>ChildField</childField>
    <parentAttr>ParentAttr</parentAttr>
</Child>

Expected

<Child childAttr="ChildAttr" parentAttr="ParentAttr">
    <childField>ChildField</childField>
</Child>
