I didn't realize we had this file.  I'm sure it's _way_ out of date with our current spec doc output.  I'm thinking we should just delete the file.  I noticed it was added in a7b7afeb9c0a65980f26b9d28bcd7e5f7c47f3de.

@dchelimsky -- what was your purpose in adding this file?  Do you see any value in keeping it?
