fwiw my version of Apache xmlbeans validate.cmd rejects this
schema as containing a UPA violation, whereas my .NET 1.1
xsd.exe command generates a nice little C# class without
batting an eyelid:
public class bar {
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("pongo")]
public string[] pongo;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("pongo")]
public string[] pongo1;
}

Subject: UPA violation or not?
Xerces reports this schema as a UPA violation, XSV reckons it is OK. Which
is correct?
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="bar">
<xs:sequence>
<xs:element ref="pongo" minOccurs="0" maxOccurs="2"/>
<xs:element ref="pongo" minOccurs="0" maxOccurs="2"/>
</xs:sequence>
</xs:complexType>
<xs:element name="doc" type="bar"/>
<xs:element name="pongo" type="xs:string"/>
</xs:schema>
Saxon 8.1 reports it as ambiguous, my current build of Saxon 8.2 doesn't (an
unintentional side-effect of an unrelated change).
My reading of the spec is that it probably is ambiguous, but that it really
doesn't need to be.
