-----------------------------------------

             Summary: SampleXmlUtil misses root element with only one child
                 Key: XMLBEANS-579
                 URL: https://issues.apache.org/jira/browse/XMLBEANS-579
             Project: XMLBeans
          Issue Type: Bug
    Affects Versions: Version 5.0.1
            Reporter: Alexander Pinske


When generating a sample, usually the top-level-element is xml-fragment. But when the type contains only one child-element, it becomes the root.

{code:java}
import org.apache.xmlbeans.SchemaTypeSystem;
import org.apache.xmlbeans.XmlBeans;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlObject;
import org.apache.xmlbeans.XmlOptions;
import org.apache.xmlbeans.impl.xb.xsdschema.SchemaDocument;
import org.apache.xmlbeans.impl.xsd2inst.SampleXmlUtil;


public class SchemaTest {


	private static String generateXml(String xsdString) throws XmlException {
		XmlOptions options = new XmlOptions().setDocumentSourceName("a.xsd");
		XmlObject xsd = SchemaDocument.Factory.parse(xsdString, options);
		SchemaTypeSystem schema = XmlBeans.compileXsd(new XmlObject[] { xsd }, XmlBeans.getBuiltinTypeSystem(), options);
		return SampleXmlUtil.createSampleForType(schema.globalElements()[0].getType());
	}


	public static void main(String[] args) throws Exception {
		String xml = generateXml(
				"<?xml version=\"1.0\" encoding=\"utf-8\"?><schema elementFormDefault=\"qualified\" targetNamespace=\"x\" xmlns=\"http://www.w3.org/2001/XMLSchema\">"
						+ "	<element name=\"a\">" //
						+ "		<complexType><sequence>" //
						+ "			<element name=\"b\"><complexType><sequence>" //
						+ "				<element name=\"c\" type=\"string\" />" //
						+ "			</sequence></complexType></element>" //
						+ "		</sequence></complexType>" //
						+ "	</element>" //
						+ "</schema>");
		System.out.println(xml);
	}
}
{code}

Generates:
{code:xml}
<x:b xmlns:x="x">
  <x:c>string</x:c>
</x:b>
{code}

Expected:
{code:xml}
<xml-fragment xmlns:x="x">
  <x:b>
    <x:c>string</x:c>
  </x:b>
</xml-fragment>
{code}
