Non-optional attributes with default value set (e.g. INTEGER with value 0) are serialized as unset ($)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create project, import model containing an entity like 
IFCDIMENSIONALEXPONENTS(0,0,0,0,0,0,0)
2. Download the model as IFC2X3, observe that the entity is serialized as 
IFCDIMENSIONALEXPONENTS($,$,$,$,$,$,$)
3. Some applications (like Solibri Model Viewer) fails to load the model.

What is the expected output? What do you see instead?

As the attributes for IFCDIMENSIONALEXPONENTS are not OPTIONAL, I expect the 
entity to be exported as IFCDIMENSIONALEXPONENTS(0,0,0,0,0,0,0) .

What version of the product are you using? On what operating system?
bimserver trunk, r1726

I have attached a patch which seems to fix this issue for the models I have 
tested so far. This checks that the attribute (StructuralFeature) is unsettable 
before checking if it is set.

BTW, this issue was reported by me, using a different gmail account.
