jboss-ejb-iiop_1_0.xsd does not match Java implementation

There's a mismatch between the schema file in
docs/schema/jboss-ejb-iiop_1_0.xsd and the java classes that implement
the parsing of this schema. As is usual in such cases, it's probably
the documentation that is wrong.

In the xsd file the children are described as attributes:

<xs:complexType name="iorTransportConfigType">
<xs:annotation>
<xs:documentation>
<![CDATA[
The iorTransportConfigType specifies attributes that can
be used to configure the transport requirements of
an IIOP enabled EJB3 bean.

• integrity: indicates if the server (target) supports
  integrity protected messages. The valid values are
  NONE, SUPPORTED or REQUIRED.
• confidentiality: indicates if the server (target)
  supports privacy protected messages. The values are
  NONE, SUPPORTED or REQUIRED.
• detect-misordering: indicates if the server (target)
  supports detection of message sequence errors. The
  values are NONE, SUPPORTED or REQUIRED.
• detect-replay: indicates if the server (target) supports
  detection of message replay attempts. The values
  are NONE, SUPPORTED or REQUIRED.
• establish-trust-in-client: indicates if the target is
  capable of authenticating a client. The values are
  NONE, SUPPORTED or REQUIRED.
• establish-trust-in-target: indicates if the target is
  capable of authenticating to a client. The values
  are NONE or SUPPORTED.

However, in the class
(org.jboss.metadata.ejb.parser.jboss.ejb3.IIOPMetaDataParser) it
requires no attributes and expects to see these same children as elements:

protected IORTransportConfigMetaData
processTransportConfig(XMLStreamReader reader, final PropertyReplacer
propertyReplacer) throws XMLStreamException {
// the transport-config element doesn't have attributes.
requireNoAttributes(reader);

EnumSet<Element> requiredElements = EnumSet.of(Element.INTEGRITY,
Element.CONFIDENTIALITY,
Element.ESTABLISH_TRUST_IN_CLIENT, Element.ESTABLISH_TRUST_IN_TARGET);

IORTransportConfigMetaData transportConfig = new
IORTransportConfigMetaData();

// process the transport config elements.
while (reader.hasNext() && reader.nextTag() != END_ELEMENT) {
Element element = Element.forName(reader.getLocalName());

// set the element text in the transport config metadata.
switch (element) {
case INTEGRITY: {
requireNoAttributes(reader);
transportConfig.setIntegrity(getElementText(reader, propertyReplacer));
break;
}
case CONFIDENTIALITY: {
requireNoAttributes(reader);
transportConfig.setConfidentiality(getElementText(reader,
propertyReplacer));
break;
}
case DETECT_MISORDERING: {
requireNoAttributes(reader);
transportConfig.setDetectMisordering(getElementText(reader,
propertyReplacer));
break;
}
case DETECT_REPLAY: {
requireNoAttributes(reader);
transportConfig.setDetectReplay(getElementText(reader, propertyReplacer));
break;
}
case ESTABLISH_TRUST_IN_CLIENT: {
requireNoAttributes(reader);
transportConfig.setEstablishTrustInClient(getElementText(reader,
propertyReplacer));
break;
}
case ESTABLISH_TRUST_IN_TARGET: {
requireNoAttributes(reader);
transportConfig.setEstablishTrustInTarget(getElementText(reader,
propertyReplacer));
break;
}
default: {
throw unexpectedElement(reader);
}
}

requiredElements.remove(element);
}

// throw an exception if a required element wasn't found.
if (!requiredElements.isEmpty()) {
throw missingRequiredElement(reader, requiredElements);
}

return transportConfig;
}
