Comments

The following schema reproduces the problem.

<?xml version = "1.0" encoding = "UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="foo">
    <xs:complexType>
      <xs:sequence>
        <xs:choice>
          <xs:sequence>
            <xs:element name="a"/>
            <xs:element name="b"/>
          </xs:sequence>
          <xs:element name="c"/>
        </xs:choice>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

Release 1.2.2 generates the following content model description:

<foo>
a, b, c | d, e
</foo>

But the correct content model would be

<foo>
a, (b, c | d), e
</foo>
