BouncingBall modelDescription.xml is not valid for trivial reasons

[Christopher Brooks <cxh@…>]

The modelDescription.xml file produced by generating a FMU for BouncingBall is not valid because some tags are empty.

To reproduce, download the FMI-2.0 xsd files and then run:

cp ~/src/openmodelica/testsuite/openmodelica/fmi/ModelExchange/2.0/BouncingBall.mos  .
omc BouncingBall.mos
xmllint --valid --schema ~/src/fmi/FMI_for_ModelExchange_and_CoSimulation_v2.0/fmi2ModelDescription.xsd modelDescription.xml

The output will be

modelDescription.xml:14: element TypeDefinitions: Schemas validity error : Element 'TypeDefinitions': Missing child element(s). Expected is ( Sim\
pleType ).
modelDescription.xml:111: element Outputs: Schemas validity error : Element 'Outputs': Missing child element(s). Expected is ( Unknown ).
modelDescription.xml:117: element InitialUnknowns: Schemas validity error : Element 'InitialUnknowns': Missing child element(s). Expected is ( Un\
known ).
modelDescription.xml fails to validate

This occurs because TypeDefinitions has no contents.

  </ModelExchange>
  <TypeDefinitions>
  </TypeDefinitions>
  <LogCategories>

FMI_for_ModelExchange_and_CoSimulation_v2.0/fmi2ModelDescription.xsd says

<xs:element name="TypeDefinitions" minOccurs="0">
  <xs:complexType>
    <xs:sequence maxOccurs="unbounded">
      <xs:element name="SimpleType" type="fmi2SimpleType"/>
    </xs:sequence>
  </xs:complexType>
</xs:element>

This is trivial, but it could mask other problems. The xml produce should be valid.

I was looking into this to see if it fixes Ticket #3170, but it does not.

Fixed in r24963.

It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.

Removing the pre1.9.4 milestone in favor of 1.9.4.
