Fix missing type reference on generated attributes for flags

[david-waltermire]

Committer Notes

Fixed a bug caused when the SchemaGenerationFeature.INLINE_DEFINITIONS is enabled causing XML schema type references to not be produced for attributes associated with flags. This change restores the correct behavior by adding a type.isGeneratedType conditional check. Resolves usnistgov/liboscal-java#181.

This issue is difficult to test for, since it involves testing a specialized schema generation configuration. A new issue has been created to work on this.

Looks good to me.

I ran the example 0.12.1 cli generated schema command versus a local build with this patch off this branch with example model and schemas in this Gist and I am able to get inline types.
