Error description

• After a UML-to-XSD transformation in IBM Rational Software
  Architect (RSA), it is not possible to specify both 'fixed' and
  'required' properties for an attribute in the XSD file.
  
  The following steps reproduce the problem:
  
  1. Create a UML project and model
  2. Apply the 'XSD Transformation', 'WSDL Transformation', and
  'SoaML' transformation to the model
  3. Add a package to the model and give it the '??schema??'
  stereotype
  4. Add a class to the package and give it the '??complexType??'
  stereotype
  5. Add an attribute to the class and give it the '??attribute??'
  stereotype
  6. Add a literal string to the attribute and give it the value,
  for example, 'x' (without the quotation marks)
  7. Set the attribute's Properties ? XSD Attribute ? Use value to
  'required', in order to generate a required value
  8. Set the attribute's Properties ? Advanced ? Is Read Only
  value to 'true', in order to generate a fixed value
  9. Create a UML-to-XSD transformation configuration (.tc) with
  the model as the Source and the project as the Target
  10. Run the .tc and examine the resulting XSD file
  
  Expected Result: Both the attribute's 'fixed = x' and
  'use=required' properties are generated.
  Actual Result: Only the 'use=required' is generated.  The
  'fixed=x' does not appear in the XSD file.
  
  11. Return to the model and set the Properties ? XSD Attribute ?
  Use value to 'optional'
  12. Repeat Step 10.
  
  Result: The 'fixed=x' is generated, but not the 'use=required'.
  It should be possible to generate both 'fixed=x' and
  'use=required' in the XSD file, but it is not.
  
  There is no workaround.

  ****************************************************************
  If a user makes an XSD attribute as 'required' from the XSD
  properties page and also makes the attribute 'fixed' by
  making it Read-Only, it is not possible to generate both
  "fixed" and "required" properties for an attribute in the
  XSD file after a UML-to-XSD transformation in IBM Rational
  Software Architect.
  

Problem conclusion

• Modified the UML-to-XSD transformation in IBM Rational
  Software Architect so that both "fixed" and "required" gets
  generated in the XSD file as specified in the model.
  

Temporary fix
