Subject: Distinguish between attributes explicitly written at the request of
 the user, and attributes implicitly generated to assist in bookkeeping by the
 compiler. This is done so by table generating a CreateImplicit method for
 each attribute.

Additionally, remove the optional nature of the spelling list index when creating attributes. This is supported by table generating a Spelling enumeration when the spellings for an attribute are distinct enough to warrant it.
