What should be written in a formal outline?

Here is my "outline" of a formal outline:

Thesis:

I. Topic Category 1
A.  Topic Sentence 1
1.  fact/support/example
2.  fact/support/example
B.  Topic Sentence 2
1.  fact/support/example
2.  fact/support/example

II. Topic Category 2
A.  Topic Sentence 3
1.  fact/support/example
2.  fact/support/example
B.  Topic Sentence 4
1.  fact/support/example
2.  fact/support/example

III. Topic Category 3
A.  Topic Sentence 5
1.  fact/support/example
2.  fact/support/example
B.  Topic Sentence 6
1.  fact/support/example
2.  fact/support/example

Understand that in the above, A,B,C etc., are complete sentences introducing the body paragraphs which support your thesis.  Use as many as is necessary.  Also, 1, 2, 3, etc., is the concrete detail that proves the topic sentence. When you translate the outline into your paper, you need to synthesize the concrete detail with commentary or explanation of the relevance to the thesis.
