NPEs resulting from null parent mapping nodes on XML Document creation from schema

While trying to create simple XML document for "Employee" from the attached Employees.xsd schema, there were NPE's.

1) Import Employees.xsd in to project
2) Select "Employee" schema element in explorer and right click "Modeling > Create XML View Documents" (XML Document Model)
3) When finished it should create a XML document with mapping classes

Tracked in Debug and seems the created MappingDocument class does not have it's variable "parent" set which is required to walk the mapping nodes and create children.
