In our codebase, we've seen cases where documentation header text contains words which are spelled correctly, but not in the correct case.
This applies to acronyms as well as proper names.
- "ID" should never be "Id"
- "SQL" should never be "Sql" or "sql"
- "Canada" should never be "canada"
There should be a way to specify this kind of thing in the custom dictionary, ideally while still using the same dictionary format as Code Analysis / FxCop.
