variable values generated for fixed elements in XSD

What steps will reproduce the problem?
1. Select a XSD with a fixed element in it. See e.g. attached file.
2. Generate instance from XSD using XSInstance
3. Validate generated instance against XSD

What is the expected output? What do you see instead?
The validation fails. I would like the validation to pass.

What version of the product are you using? On what operating system?
The latest version from the svn archieve.
On windows.
